qcacld-3.0: Protect set_thermal_mitigation with dsc psoc sync

Browse source 
Currently, the operation set thermal mitigation which is invoked
from PLD is not dsc protected. As a result it is causing a memory
leak issue when there is an idle shutdown is happening in parallel.

To avoid this, protect set thermal mitigation operation with dsc psoc
sync.
