[ 41/52] dm-raid: silence compiler warning on rebuilds_per_group.

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: NeilBrown <neilb@xxxxxxx>

commit 3f6bbd3ffd7b733dd705e494663e5761aa2cb9c1 upstream.

This doesn't really need to be initialised, but it doesn't hurt,
silences the compiler, and as it is a counter it makes sense for it to
start at zero.
