xfs: remove xfs_buf_cache.bc_lock
xfs_buf_cache.bc_lock serializes adding buffers to and removing them from
the hashtable. But as the rhashtable code already uses fine grained
internal locking for inserts and removals the extra protection isn't
actually required.
It also happens to fix a lock order inversion vs b_lock added by the
recent lookup race fix.
