Revert "qcacld-3.0: Acquire wake lock timeout for rrm scan"

FW does not assert when wow is enabled in presence of active
scans. Only requirement is to abort the scans while suspending.
So holding wakelock till scan is complete may introduce power
side effects.

Aborting the scan while suspending is already taken care by
the CR-2343385.

Fix is to revert the
Change Id: I02ddc9b5e6ba5f1782d00e34f044ace34c54d0b0 and
cleanup the channel list from rrm context in case of failure
of rrm scan req.
