wifi: ath12k: fix uninitialize symbol error on ath12k_peer_assoc_h_he()
[ Upstream commit 19b77e7c656a3e125319cc3ef347b397cf042bf6 ]
Smatch throws following errors
drivers/net/wireless/ath/ath12k/mac.c:1922 ath12k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.
drivers/net/wireless/ath/ath12k/mac.c:1922 ath12k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_160'.
drivers/net/wireless/ath/ath12k/mac.c:1924 ath12k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.
In ath12k_peer_assoc_h_he() rx_mcs_80 and rx_mcs_160 variables
remain uninitialized in the following conditions:
1. Whenever the value of mcs_80 become equal to
IEEE80211_HE_MCS_NOT_SUPPORTED then rx_mcs_80 remains uninitialized.
2. Whenever phy capability is not supported 160 channel width and
value of mcs_160 become equal to IEEE80211_HE_MCS_NOT_SUPPORTED
then rx_mcs_160 remains uninitialized.
Initialize these variables during declaration.
