Vhost-User: Fix calculate memory region size

The memory region size calculation is wrong. For example, a region
with size of 1G (hugepage size is also 1G), and offset is zero, use
the previous way to calculate, the ultimate size to mmap and munmap
is 2G, which could lead to segment fault when munmap is executed.

This patch refers the way in DPDK to calculate the region size.
