qcacld-3.0: Remove wlan_hdd_check_remain_on_channel() API

The wlan_hdd_check_remain_on_channel() is a wrapper API around
wlan_hdd_cancel_existing_remain_on_channel() with an additional
opmode check. Perform this opmode check to caller.

The wlan_hdd_cancel_existing_remain_on_channel() reimplements
wlan_hdd_cleanup_remain_on_channel_ctx(), so remove this API
and move existing callers to wlan_hdd_cleanup_remain_on_channel_ctx().
