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

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.
