This patch handles case where raid hidden components
are not being removed when power turned off to device
attached to expander, as well as the case of
exposing raid components when power is turned back on
to devices attached to an expander. (This is a repost
of this patch, with mptsas_is_end_device declared
further up in the code.)
This patch contains some other miscellaneous bug fix's.
