    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.
