qcacld-3.0: enabled EXT GRP IRQs after power save exit

Browse Source 
Currently in the WoW design of Moselle, EXT GRP IRQs are
enabled before sending SMP2P power save exit message is
sent to the FW. Because of this, any pending IRQs in the
GIC will immediately fire and could race with the SMP2P
power save exit logic. Any access to the registers done
before power save exit would result in system errors.
Enable the EXT GRP IRQs after sending power save exit
command will fix the problem.
