[libvirt] [PATCH] qemuDomainCleanupRemove: s/memmove/VIR_DELETE_ELEMENT_INPLACE/

[Michal Privoznik]

The last argument of memmove is the amount of bytes to be moved. The
amount is in Bytes. We are moving some void pointers around. However,
since sizeof(void *) is not Byte on any architecture, we've got the
arithmetic wrong.
