Ovirt devel - Aug 2011 - [PATCH node] handle wildcards appropriately in dracut plugin

when specifying a list of devices, one with a wildcard, the dracut
plugin would attempt to use all devices matching the wildcard
instead of just the first device.

Ex.  storage_init=/dev/vd*,/dev/sda
should match /dev/vda and /dev/sda only, but if /dev/vdb, /dev/vdc
etc existed, it would match all of those as well.
