ivshmem: Don't make IVSHMEMEvtDeviceReleaseHardware pageable
ivshmem: Don't make IVSHMEMEvtDeviceReleaseHardware pageable

The function takes a lock which raises IRQL to DISPATCH_LEVEL so the
code must be in non-pageable memory. This eliminates a build warning:

c:\kvm-guest-drivers-windows\ivshmem\device.c(236): warning C28150: The function 'KeAcquireSpinLockRaiseToDpc' causes the IRQ Level to be set above the maximum acceptable for the function being analyzed:
The level limits come from being PAGED_CODE or annotations on the current function. [C:\kvm-guest-drivers-windows\ivshmem\ivshmem.vcxproj]
