[PATCH] dracut: Verify multipath config_dir option

["Milan P. Gandhi" <mgandhi-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

The 90multipath/module-setup.sh file currently does not check the
dm-multipath config_dir option. This option in multipath.conf file is
used to specify a custom directory/path that contains the multipath
configuration files. It's default value is /etc/multipath/conf.d

Currently install function of module-setup.sh has hardcoded the above
path, but users could change it with config_dir option. So, adding a
command to get the directory specified with config_dir option and add
these configuration files to the initial ram disk image.
