When ProcXkbSetNamedIndicator is called on a core device, and we
walk the slaves to set the LED's on each of them, ignore any slaves
that do not have either a KbdFeedbackCtrl or LedCtrl structure.
(This is much more critical in xserver-1.5-branch, where we walk
*all* devices, not just the slaves of the specified master, and
thus return failure when setting an LED on the Core Keyboard and
hit a xf86-input-mouse device with no LED's to set.)
