[PATCH linux-next] DM RAID: validate_raid_redundancy: Silence uninitialized variable warning

From: Tim Gardner
Date: Wed Feb 20 2013 - 15:31:48 EST

drivers/md/dm-raid.c: In function 'raid_ctr':
drivers/md/dm-raid.c:453:53: warning: 'rebuilds_per_group' may be used uninitialized in this function [-Wuninitialized]
drivers/md/dm-raid.c:383:11: note: 'rebuilds_per_group' was declared here

It appears unlikely that rebuilds_per_group could be used before set, but set
it to 0 anyways just to shutup GCC.
