[libvirt] [PATCH] qemu: panic device: check for invalid address type

[Erik Skultety]

qemu now checks for invalid address type for a panic device, which is
currently implemented only to use ISA address type, thus rejecting
any other options, except for leaving XML attributes blank, in that case,
defaults are used (this behaviour remains the same from earlier verions).
