Konstantin Belousov ca109b01cf When non-forced unmount or remount rw->ro is performed, writes on UFS
are not suspended.  In particular, on the SU-enabled vulumes, there is
no reason why, between the call to softdep_flushfiles() and
softdep_waitidle(), SU work items cannot be queued.

Correct the condition to trigger the panic by only checking when
forced operation is done.  Convert direct panic() call into KASSERT(),
there is no invalid on-disk data structures directly involved, so
follow the usual debugging vs. non-debugging approach.
