[PATCH 24/23] md: remove slashes from disk names when creation dev names in sysfs

[Chris Wright <chrisw@sous-sol.org>]

-stable review patch.  If anyone has any objections, please let us know.
(this should've been in the series.  i missed this one, mea culpa)
------------------

e.g. The sx8 driver uses names like sx8/0.

This would make a md component dev name like

   /sys/block/md0/md/dev-sx8/0

which is not allowed.  So we change the '/' to '!' just like
fs/partitions/check.c(register_disk) does.
