gfs2 umount: support fake -r option

Hi guys,

in certain situations where gfs2 init scripts are not used to umount gfs2 volume, we endup with umount.gfs2 being invoked with -r option and this fails because we don't know what to do with this option.

The patch simply ack the option and ignores it for now allowing a reboot process to keep going.

Please ACK or apply.

Fabio
