btrfs: convert __TRANS_* defines to enum bits
The base transaction bits can be defined as bits in a contiguous sequence, although right now there's a hole from bit 1 to 8. The bits are used for btrfs_trans_handle::type, and there's another set of TRANS_STATE_* defines that are for btrfs_transaction::state. They are mutually exclusive though the hole in the sequence looks like was made for the states. Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
