Adds a case for NotifyData_data_jobDispatchFail to sched_handle_notify()'s
switch, fixing bug-1625 -- the notify was previously silently discarded
(falling to default: -EINVAL), leaving job->accounts/job->allocs stale
forever on any dispatch failure. No classification logic here: the
controller has already decided PEND is correct before sending the notify;
this reuses the same XCE_SCHED_OP_JSTATE_CHANGE enqueue path the adjacent
schedExitJob/schedFailJob cases already use, and relies on core_events.c's
existing free-on-non-RUN branch to release the stale accounts/allocs.
Independently reviewed and approved: full scheduler suite passes (51/52,
one pre-existing unrelated flake -- bug-1560).
