Stefan Hajnoczi 314aec4a6e hostmem-file: reject invalid pmem file sizes ...

Guests started with NVDIMMs larger than the underlying host file produce
confusing errors inside the guest.  This happens because the guest
accesses pages beyond the end of the file.

Check the pmem file size on startup and print a clear error message if
the size is invalid.
