qemu: Use correct domain xml flag
qemu: Use correct domain xml flag

Although VIR_DOMAIN_DEF_FORMAT_INACTIVE and VIR_DOMAIN_XML_INACTIVE
happen to have the same value (1<<1), they come from different enums;
and it is nicer to reason about a 'flags' variable if all uses of
that variable are compared against the same enum type.  Messed up in
commit 06f75ff2 (3.8.0).
