Subject: [PATCH] wifi: ath12k: sanitize ath12k_mac_allocate() return code

From: Arnd Bergmann <arnd@...db.de>

The return code has no initializer:

drivers/net/wireless/ath/ath12k/mac.c:8006:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]

Make it return -ENOMEM for allocation failures and remove the unused
variable instead.

Fixes: 6db6e70a17f6 ("wifi: ath12k: Introduce the container for mac80211 hw")
