Michael Lyle f9f175778b bcache: check return value of register_shrinker
[ Upstream commit 6c4ca1e36cdc1a0a7a84797804b87920ccbebf51 ]

register_shrinker is now __must_check, so check it to kill a warning.
Caller of bch_btree_cache_alloc in super.c appropriately checks return
value so this is fully plumbed through.

This V2 fixes checkpatch warnings and improves the commit description,
as I was too hasty getting the previous version out.
