[PATCH 3/4] bus/vmbus: Use Hyper-V page size for mapping to UIO pages

[longli at linuxonhyperv.com]

From: Long Li <longli at microsoft.com>

The interrupt and monitor pages mapped from Hyper-V via kernel are always
4k in sizes. Use Hyper-V page size to map them.

Fixes: 831dba47bd ("bus/vmbus: add Hyper-V virtual bus support")
