Subject: [PATCH] bcache: fix compilation warning

The release function of a block device does not return a value; make
release_dev void. This fixes the following warning:

drivers/md/bcache/super.c:653:2: warning: initialization from incompatible pointer type [enabled by default]
drivers/md/bcache/super.c:653:2: warning: (near initialization for ‘bcache_ops.release’) [enabled by default]
