btrfs: transaction_kthread() is not freezable
transaction_kthread() is calling try_to_freeze(), but that's just an expeinsive no-op given the fact that the thread is not marked freezable. After removing this, disk-io.c is now independent on freezer API. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: David Sterba <dsterba@suse.com>
