from frame data for WDS only if WDS condition is valid.
The other optimization is to avoid accessing queue_mapping

In some corner case, host has done Vdev destroy and TX desc flush
since there is pending outstanding TX data on this vdev, but later
FW/HW still indicate the TX completion to host and which likely
these TX completion get delayed, conflict happened due to same TX
Desc accessing.
To fix it:
(1) Only reset TX desc Vdev to NULL in dp_tx_vdev_detach().
(2) Do more enhancement in dp_tx_comp_handler() to avoid
invalid Vdev accessing.
(3) Do TX desc flush in dp_tx_pdev_detach().

Deadlock happens when control path takes scn_lock and calls
dp_peer_unref_delete() which in tern tries to acquire peer_ref_mutex.
At the same time, if other core starts handling peer_unmap by acquiring
peer_ref_mutex and calls dp_reset_and_release_peer_mem() which in turn
calls ol_ath_node_free() and tries to acquire scn_lock leading to a
deadlock.
Fix this by unlocking peer_ref_mutex before calling

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.
