Pankaj Raghav e5cc78e9db Kernel: Add m_reserved private variable to GenericInterruptHandler ...

Pin-based PCI device are allocated an IRQ, and it could be shared with
multiple devices. An interrupt handler with an IRQ for a PCI device
will get registered only during the driver initialization.

For MSI(x) interrupts, the driver has to allocate IRQs and this field
can be used to skip IRQs that have already been reserved by pin-based
interrupts so that we don't have to share IRQs, which generally will
reduce the performance.
