virtio-mem: Make sure "usable_region_size" is always multiples of the block size
The spec states:
"The device MUST set addr, region_size, usable_region_size, plugged_size,
requested_size to multiples of block_size."
With block sizes > 256MB, we currently wouldn't guarantee that for the
usable_region_size.
Note that we cannot exceed the region_size, as we already enforce the
alignment there properly.
