[Xen-devel] [patch] qemu-xen: pass-through: Allow slots 1e and 1f to be used

[Simon Horman <horms@xxxxxxxxxxxx>]

This fixes an oversight in my recent patch "Allow any unused PCI device to
be used for pass-through" whereby attempts to use slots 1e and 1f for
pass-through would silently fail.

* This affects both static and manual selection of slots
* This affects both hot-plug and static pass-through
