PATCH: do not try to activate isw raidsets with dmraid, unless noiswmd is present on the cmdline

Do not try to activate isw raidsets with dmraid, unless noiswmd is present on the cmdline.

This patch also replaces:
/sbin/dmraid -ay -i -p -t | <complicated grep + awk>

With a simple:
/sbin/dmraid -s -c -i

Which besides being simpler also has the advantage of not listing subsets
of layer raids (such as raid10) so that we do not try to activate individual
subsets (which fails, and shows ugly error messages).

Note we need todo the same (use /sbin/dmraid -s -c -i) for RHEL-5, I'll file
a separate bug for this.
