[Xen-devel] [patch] Fix xm pci-detach for inactive devices

[Simon Horman <horms@xxxxxxxxxxxx>]

In the case where a device is attached to an inactive domain
and then removed before the domain is activated it won't have
a vslot assigned, but it should still be valid to remove it.

I don't think that there are any other cases where vslot can
be invalid.

Lightly tested
