qcacmn: Don't clear the interupt status when rx_pending

Browse source 
If there is rx pending, the per_engine_service caller should
not reenable interrupts.  If the caller does propper interrupt
mitigation, it will not enable interrupts, and the register
write is wasted.  If the caller does not do interrupt mitigation,
leaving the interupt status will prevent stuck packets.
