GFS2: Add commit= mount option
It has always been possible to adjust the gfs2 log commit interval, but only from the sysfs interface. This adds a mount option, commit=<nn>, which will be familar to ext3 users. The sysfs interface continues to be available as well, although this might be removed in the future. Also this patch cleans up some duplicated structures in the GFS2 sysfs code.
