block: Respect underlying file's EOF
When falling through to the underlying file in bdrv_co_get_block_status(), if it returns that the query offset is beyond the file end (by setting *pnum to 0), return the range to be zero and do not let the number of sectors for which information could be obtained be overwritten.
