[PATCH] qemu: domainjob: Allow free if cb is not set in qemuDomainObjClearJob
We should allow resetting and freeing qemuDomainJobObj even if
'cb' attribute is not set. This is theoretical for now, but the
attribute must not be always set in the future, so early return
would create memory leaks. It is sufficient to check if 'cb'
exists before dereferencing it in qemuDomainObjClearJob() and
also qemuDomainObjResetAsyncJob() as the latter is called from
the former.
This commit partially reverts af16e754cd4efc3ca1.
