block/vhdx: check error return of bdrv_getlength()
Calls to bdrv_getlength() were not checking for error. In vhdx.c, this
can lead to truncating an image file, so it is a definite bug. In
vhdx-log.c, the path for improper behavior is less clear, but it is best
to check in any case.
Some minor code movement of the log_guid intialization, as well.
