[lvc-project] [PATCH 1/2] wifi: ath12k: annotate skb of struct ath12k_ce_ring with __counted_by

[Dmitry Antipov]

Accorind to 'ath12k_ce_alloc_ring()', annotate flexible array
member 'skb' of 'struct ath12k_ce_ring' with '__counted_by()'
to improve runtime bounds checking when CONFIG_UBSAN_BOUNDS is
enabled. Compile tested only.
