[libvirt PATCH 4/4] virDomainObjGetState: Promote VIR_DOMAIN_PAUSED_POSTCOPY_FAILED

[Jiri Denemark <jdenemar@xxxxxxxxxx>]

In case a domain is in failed post-copy migration but paused for a
different reason, report VIR_DOMAIN_PAUSED_POSTCOPY_FAILED instead to
make it more visible.

    because I can find reasons for both pushing and not pushing this change.
    It is pretty ugly and masks the real reason behind the paused state. On
    the other hand, reporting the real reason means users would not really
    know post-copy migration failed unless they saw the corresponding event.
