cam_xpt.diff
Change periph to next_periph inside of a couple of loops, so that the loops
skip over periphs that have CAM_PERIPH_FREE set, rather than spin forever and
deadlock CAM by never releasing a mutex. Looks like a copy&paste bug from some
other loops that iterated over periph rather than next_periph.
