block: mirror - change string allocation to 2-bytes
The backing_filename string in mirror_run() is only used to check for a NULL string, so we don't need to allocate 1024 bytes (or, later, PATH_MAX bytes), when we only need to copy the first 2 characters. We technically only need 1 byte, as we are just checking for NULL, but since backing_filename[] is populated by bdrv_get_backing_filename(), a string size of 1 will always only return '\0'; Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com> Signed-off-by: Jeff Cody <jcody@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
