PCI: qcom-ep: Drop the redundant masking of global IRQ events

Browse Source 
Once the events are disabled in PARF_INT_ALL_MASK register, only the
enabled events will generate global IRQ. So there is no need to do the
masking again in the IRQ handler, drop it.

If there are any spurious IRQs getting generated, they will be reported
using the existing dev_err() in the handler.
