rbd: remove buggy rollback functionality
This doesn't interact with resizing well, since it doesn't set the size of the device to the size at the snapshot. It's also an expensive operation to be synchronous. Rollback can still be done with the userspace rbd tool. Signed-off-by: Josh Durgin <josh.durgin@dreamhost.com>
