[PATCH v1] qemu: save status xml after generating taint message

[Kristina Hanicova <khanicov@xxxxxxxxxx>]

We didn't always save status xml after generating new taint
message, which resulted in it being deleted in case of a libvirtd
restart.  Some taint messages were preserved thanks to saving
status xml separately at the end of the calling functions (which
makes sense, because qemuDomainObjTaint was usually called there
multiple times).  But for special cases (e.g. When only few taint
messages are generated) we need a separate function for
generating them and saving status xml explicitly.

Resolves:
