wlan: Return appropriate value for SETBAND request

If SETBAND is issued by VENDOR command, then it expects SUCCESS/FAILURE
status, but if SETBAND is issued by IOCTL, then it expects
CHANNEL_CHANGE_EVENT.
Hence return appropriate value when SETBAND is issued, depending up on
from where request is coming.
