wifi: ath12k: Fix uninitialized use of ret in ath12k_mac_allocate()

Browse Source 
Clang warns (or errors with CONFIG_WERROR=y):

  drivers/net/wireless/ath/ath12k/mac.c:8060:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]
   8060 |         return ret;

  drivers/net/wireless/ath/ath12k/mac.c:8022:9: note: initialize the variable 'ret' to silence this warning

Commit 6db6e70a17 ("wifi: ath12k: Introduce the container for mac80211
hw") added a completely uninitialized use of ret. Prior to that change,
-ENOMEM was returned to the callers of ath12k_mac_allocate() whenever
ath12k_mac_hw_allocate() failed. Assign that value to ret to make sure
it is always initialized when used and clear up the warning.
