wifi: mt76: connac: tolerate inactive BSS deactivation

Browse Source 
Firmware may return wlan_failure when deactivating a BSS that is already
inactive. This is a valid teardown case and should not fail the remove
path.

Keep activation failures unchanged since they still indicate that firmware
failed to create or activate the BSS state.
