qemu: Introduce qemuDomainRemoveInactiveJobLocked

Create a qemuDomainRemoveInactiveJobLocked which copies
qemuDomainRemoveInactiveJob except of course calling
another new helper qemuDomainRemoveInactiveLocked.

The qemuDomainRemoveInactiveLocked is a copy of
qemuDomainRemoveInactive except that instead of calling
virDomainObjListRemove it calls virDomainObjListRemoveLocked.
