wifi: ath11k: fix SAC bug on peer addition with sta band migration

Browse source

[ Upstream commit 60b7d62ba8 ]

Fix sleep in atomic context warning detected by Smatch static checker
analyzer.

Following the locking pattern for peer_rhash_add lock tbl_mtx_lock mutex
always even if sta is not transitioning to another band.
This is peer_add function and a more secure locking should not cause
performance regression.
