Log Message:
In the case of a shared GSI, bind will fail, so we do not attempt this.
The sharing is accomplished by demultiplexing the port event of the first
bind. This is accomplished in intr.c:intr_establish_xname()

Note that the pic_delroute() is buggy (commented suitably) for the shared
gsi case, since it will unbind reset it unconditionally, leaving the other
shared callbacks stranded.

This problem will go awaywhen we unify further with native code, as this
case is taken care of appropriately in that case.
