Sergey Senozhatsky ace8577aeb block_dev: Suppress bdev_cache_init() kmemleak warninig

due to attempt to mark pointer to `struct vfsmount' as a gray object, which
is embedded into `struct mount' returned from alloc_vfsmnt().

Make `bd_mnt' static, avoiding need to tell kmemleak to mark it gray, as
suggested by Al Viro.
