wifi: ath: work around false-positive stringop-overread warning
In a rare arm64 randconfig build, I got multiple warnings for ath11k
and ath12k:
In function 'ath11k_peer_assoc_h_ht',
inlined from 'ath11k_peer_assoc_prepare' at drivers/net/wireless/ath/ath11k/mac.c:2665:2:
drivers/net/wireless/ath/ath11k/mac.c:1709:13: error: 'ath11k_peer_assoc_h_ht_masked' reading 10 bytes from a region of size 0 [-Werror=stringop-overread]
1709 | if (ath11k_peer_assoc_h_ht_masked(ht_mcs_mask))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This happens whenever gcc-13 fails to inline one of the functions
that take a fixed-length array argument but gets passed a pointer.
Change these functions to all take a regular pointer argument
instead.
