uio_hv_generic: Use correct size for interrupt and monitor pages
Interrupt and monitor pages should be in Hyper-V page size (4k bytes).
This can be different from the system page size.
This size is read and used by the user-mode program to determine the
mapped data region. An example of such user-mode program is the VMBus
driver in DPDK.
