qemu: refresh internal domain state after reset

Internal domain state may change during the reset and qemu does
not always send events about it.  In case it happens, internal
state of the domain in libvirt would be inconsistent with the
internal state in qemu which could cause additional problems
(e.g. cdrom tray state can change from open to closed).  The
solution is to refresh state after a successful reset to query
qemu about the current internal domain state.
