[PATCH] qemu: fix wrong remove guest cfg if migrate fail

[Luyao Huang <lhuang@xxxxxxxxxx>]

If we get fail in qemuMigrationPrepareAny, we forget
check if the vm is persistent then always call
qemuDomainRemoveInactive to clean the inactive settings.
Add a check to avoid this. This issue was introduce in
commit 540c339.
