qemu: Init ext devices paths on reconnect

Browse Source 
Paths for external devices (well, so far only vTPM) are not
stored in the status XML. Therefore, we need to regenerate them
after we've been restarted and reconnecting to a running domain.
Otherwise these will remain NULL which may later lead to a NULL
dereference.
