[PATCH 3/7] bcachefs: Fix triggering of discard by the journal path

It becomes possible to do discards after a journal flush, which
naturally the journal code is reponsible for.

A prior refactoring seems to have broken this - which went unnoticed
because the foreground allocator path can also trigger discards.
