Btrfs: convert the inode bit field to use the actual bit operations
Miao pointed this out while I was working on an orphan problem that messing with a bitfield where different ranges are protected by different locks doesn't work out right. Turns out we've been doing this forever where we have different parts of the bit field protected by either no lock at all or different locks which could cause all sorts of weird problems including the issue I was hitting. So instead make a runtime_flags thing that we use the normal bit operations on that are all atomic so we can keep having our no/different locking for the different flags and then make force_compress it's own thing so it can be treated normally.
