Subject: [PATCH] Change behavior in find_free_devnm when wrapping around.
Git-commit: 2e466cce45ac2397ea426a765c829c621901664b
Patch-mainline: mdadm-4.0-84
References: bsc#1009954

Newer kernels don't allow for specifying an array larger than 511. This
makes it so find_free_devnm wraps to 511 instead of 2^20 - 1.
