[roll] Roll fuchsia [fxfs] Fix some locking issues

Taking the same read lock twice can lead to deadlocks.  The journal was
doing this with the filesystem lock.

There was a lock ordering issue between the filesystem lock and the
flush lock.

I took the opportunity to refactor things so that you can't take read
locks with the transaction since it had odd ordering semantics.
