qdf_set_pkt_len will invoke pskb_expand_head to renew skb->head

Crash scenario:
(1) frag data A is dropped and related RX desc A is replenished
and reused, but pdev->free_list_tail is still pointed to RX desc A.
(2) frag data B/C is coming, defrag fails then pdev->free_list_head
will point to B-->C RX desc, but pdev->free_list_tail still point to A.
(3) for defrag failing case, host only will replenish 1 RX buffer for
current case, RX desc B is replenished, while C will be free back to
RX desc pool.
(4) dp_rx_add_desc_list_to_free_list will set RX desc A-->next =
free_list, free_list point to C insted.
(5) when step (1) RX desc A replenished buffer indicated to host by
REO2Dst ring, RX desc A -->nbuf actually is pointed to another RX
desc, invalid skb accessing will happen.
Solution:
a. reset tail pointer in dp_rx_add_desc_list_to_free_list at last.
b. reset tail pointer same as head in dp_rx_add_to_free_desc_list
if head->next is NULL.
c. set correct rx_bufs number for replenish when dp_rx_defrag fails.

Currently defragmented packets use HAL_RX_BUF_RBM_SW1_RBM as the RBM
value for the defragmented packets which are re-injected into REO.
Thus, if REO encounters any error while handling these packets, they
would end up in WBM2SW1 ring (via WBM), which is managed by the FW. The
FW will eventually recycle these buffers back to RXDMA via its refill
process. As a part of defragmentation, host does a 802.11 -> 802.3
header conversion. This is resulting in an address which is not 4
byte aligned. Hence, when RXDMA tries to use these addresses (after FW
recycles them), it may lead to issues.
Change the RBM value of the defragmented buffers which are
re-injected. Now, if REO ends up throwing an error for these
packets, they wll end up in WBM2SW3, which is managed by the host.
The host can then drop these packets and replenish RXDMA with 4 byte
aligned buffers (via FW).

CCE stats are reported across rings today. Since HKv2 is a SMP, it
creates the possibility of missing stats when two or more CPUs are
updating the counters for the same protocol type. In order to avoid
this, we can either use locks or store stats on a per-CPU basis.
Since tagging happens on the core data path, locks are not preferred.
Instead, we use a per-ring counter, since each CPU operates on a REO
ring. Exception packets today go to Ring-0 (also normal rx Reo-0
go to Ring-0). Hence tags are maintained separately for exception
ring as well.

With this feature, using appropriate commands, link layer, network layer,
transport layer and some of the application protocols can be tagged with
the user provided tag values for easier identification of protocols. The
supported protocols today are as follows.
ARP, DHCPv4, DHCPv6, DNS over TCP (v4), DNS over TCP (v6), DNS over UDP
(v4), DNS over UDP (v6), ICMPv4, ICMPv6, TCPv4, TCPv6, UDPv4,
UDPv6, IPv4, IPv6, EAP.
Receive packets are tagged by hardware. Tags are applied after the first
matching rule. Hence it is recommended that the rules are
programmed in such a way that tags are configured from application layer
to data link layer to get expected results.
