qcacld-3.0: Remove pm_freezing check from psoc idle restart

pm_freezing check to abort system suspend during psoc idle
restart is not working and hence remove pm_freezing check.
Correct fix(change Ib89eca5014729f6a2103e14c6f46540d1406a5a0)
to reliably abort system suspend by calling qdf system awake
api during psoc idle restart is already present so pm_freezing
check is no longer needed.
