[PATCH] diskfilter: Treat an unrecognized RAID level as an error

[Richard Laager]

disk/diskfilter.c: In function 'grub_diskfilter_make_raid':
disk/diskfilter.c:847:21: error: 'totsize' may be used uninitialized in
this function [-Werror=uninitialized]

Perhaps my patch should use assert() instead of return NULL?
