btrfs: refactor priority_reclaim_metadata_space
With the eviction flushing stuff we'll want to allow for different
states, but still work basically the same way that
priority_reclaim_metadata_space works currently. Refactor this to take
the flushing states and size as an argument so we can use the same logic
for limit flushing and eviction flushing.
