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.
