5 GHz band channel 177 support was added with the commit "wifi: ath11k: add channel 177 into 5 GHz channel list". However, during processing for the received ppdu in ath11k_dp_rx_h_ppdu(), channel number is checked only till 173. This leads to driver code checking for channel and then fetching the band from it which is extra effort since firmware has already given the channel number in the meta deta. Fix this issue by checking the channel number till 177 since we support it now. Found via code review. Compile tested only.
