bcachefs: Inline btree write buffer sort
The sort in the btree write buffer flush path is a very hot path, and
it's particularly performance sensitive since it's single threaded and
can block every other thread on a multithreaded write workload.
It's well worth doing a sort with inlined cmp and swap functions.
