check_disk behaviour for SAN hiccups

[Voon, Ton]

Jim,

Thanks for the report. I've made a patch for r1_3_0, check_disk v 1.7.2.3,
so that it will return critical if the filesystem is missing.

Note that it will return critical if you specify only one filesystem. For
multiple fs (eg, -p "/ /ora_backup /tmp"), it will still return only a
warning. I'm thinking of a neater solution for the 1.4 release.
