[lvc-project] [PATCH] wifi: ath11k: drop NULL pointer check in ath11k_update_per_peer_tx_stats()

Since 'user_stats' is a fixed-size array of 'struct htt_ppdu_user_stats'
in 'struct htt_ppdu_stats', any of its member can't be NULL and so
relevant check may be dropped.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
