[PATCH i-g-t 0/1] lib/xe/xe_query: Wait for xe_supports_faults

[Jonathan Cavitt]

It's possible for xe_supports_faults to return false if the system is
busy with multiple running tests.  This is because the check looks for
all active VMs and searches for VMs that do not have faults enabled,
returning false if any exist.  Recently, this check has been changed to
return EBUSY when the check fails in this way, so wait for up to ten
seconds for all the active VMs to flush out before proceeding.
