Linux 5.11 compat: bdev_whole()
The bd_contains member was removed from the block_device structure.
Callers needing to determine if a vdev is a whole block device should
use the new bdev_whole() wrapper. For older kernels we provide our
own bdev_whole() wrapper which relies on bd_contains for compatibility.
