SVN rev 192535 on 2009-05-21 13:22:07Z by attilio
Move the M_WAITOK flag in notify() into an M_NOWAIT one in order to match
the behaviour alredy present with the further malloc() call in
devctl_notify().
This fixes a bug in the CAM layer where the camisr handler finished to
call camperiphfree() (and subsequently destroy_dev() resulting in a new
dev notify) while the xpt lock is held.
