[Qemu-devel] [PATCHv2] qemu-img: add special exit code if bdrv_check is not supported

[Peter Lieven <pl@kamp.de>]

currently it is not possible to distinguish by exitcode if there
has been an error or if bdrv_check is not supported by the image
format. Change the exitcode from 1 to 63 for the latter case.

v1->v2: As Eric suggested changed the exitcode from 255 to 63.
