dm kcopyd: fix job_pool leak
Fix memory leak introduced by commita6e50b409d
(dm snapshot: skip reading origin when overwriting complete chunk). When allocating a set of jobs from kc->job_pool, job->master_job must be set (to point to itself) so that the mempool item gets freed when the master_job completes. master_job was introduced by commitc6ea41fbbe
(dm kcopyd: preallocate sub jobs to avoid deadlock) Reported-by: Michael Leun <ml@newton.leun.net> Cc: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
