bcachefs: Fix locking in btree_node_write_done()

There was a rare recursive locking bug, in __bch2_btree_node_write()
nowrite path -> btree_node_write_done(), in the path that kicks off
another write.

This splits out an inner __btree_node_write_done() that expects to be
run with the btree node lock held.
