wifi: ath12k: clear dangling channel pointers on error paths

Browse source

On failure, ath12k_mac_setup_channels_rates() frees band channel
arrays but leaves the pointers set, or clears the wrong band after a
copy-paste typo (6 GHz free paired with a 2 GHz NULL). Clear the
matching sbands[].channels pointer after each kfree().

Compile tested only.
