btrfs: dev-replace: remove unused members of btrfs_dev_replace
Lock owner and nesting level have been unused since day 1, probably copy&pasted from the extent_buffer locking scheme without much thinking. The locking of device replace is simpler and does not need any lock nesting. Signed-off-by: David Sterba <dsterba@suse.com>
