qemu: block-commit: Mark disk in block jobs only on successful command

Patch 51f9f03a4ca50b070c0fbfb29748d49f583e15e1 introduces a regression
where if a blockCommit operation fails the disk is still marked as being
part of a block job but can't be unmarked later.

(cherry picked from commit ee744b5b387b5123ee40683c52ab40783ffc3020)
