Add pdev checking when processing the htt completion messages to avoid
NULL pointer dereference both in the dp_tx_process_htt_completion and
dp_tx_comp_handler.

Optimize tx completion processing in fastpath by adding the list of
tx descs to the free list directly instead of individually accessing
each descriptor and adding it to free list. This gives advantages of
not taking descriptor pool lock for each descriptor and rather takes
the lock only once when appending the whole list of descs to the
free list.
Also removed unused member shinfo_addr from tx_desc structure. Removal
of this member enables increase of flags type from u16 to u32 without
increasing the size of tx_desc structure. These changes improved peak
KPI by 2% in SFE mode.

1. In lowmem profiles the number of tx_desc in 4th pool is reduced to
quarter for memory optimizations.
Added new API dp_get_updated_tx_desc which will return the desc value
from INI based on the flag DP_TX_DESC_POOL_OPTIMIZE.
2. Changes to introduce new INI to get reduced desc value for 4th tx
desc pool.
This helps optimize 0.75M per SOC in lowmem profiles.

This flag DP_TX_EXT_DESC_POOL_OPTIMIZE if enabled will reduce the number
of ext tx desc pool to 1.
1. Changes done to split the tx_desc and ext_tx_desc pool number
variables in alloc and free path. Based on this flag the reduced
ext_desc_pool count will be returned.
2. In Tx path, since the pool id is selected based on the CPU, changes done
to override the desc_pool_id of ext_desc_pool via new API
dp_tx_ext_desc_pool_override to 0 with which from whatever core the packets
comes from, pool 0 will be chosen for ext_desc.

In case when repeater is not supported for TX multipass,

The to_fw bit in HW descriptor is not set for exception
marked skb that is scattered across multiple pages. In the
case of direct link, this would result in crash as TQM
bypass mode is used for direct link vdev.
Fix is to set the to_fw bit to 1 in HW descriptor for
exception marked skb.

Currently the packet tx handling for AP-multipass
assumes wlan repeater to be present. For targets like
qca6490, kiwi etc, wlan repeaters are not supported in
the network topology.
Hence to skip unwanted tx packet copy in per-pkt path,
move the code to handle packet tx to waln repeater in
multipass mode under a feature macro.

Tx completion is processed in napi context, which should follow
napi's max quota, otherwise once process count is over napi quota,
it will trigger napi repoll in kernel, meanwhile by current design,
tx completion hard irq will be enabled when the 1st napi process
finished, in such case 2nd napi process will conflict with repoll process,
finally trigger kernel side napi list crash.
Since napi quota is used in serval cases, while for tx completion
process, we want to process tx completion count as many as possbile
in one cycle, set 64k transmit frames account for 1 napi work unit
to gain max tx kpi.
