bcachefs: BCH_WRITE_SYNC

This adds a new flag for the write path, BCH_WRITE_SYNC, and switches
the O_DIRECT write path to use it when we're not running asynchronously.

It runs the btree update after the write in the original thread's
context instead of a kworker, cutting context switches in half.
