For all the callers of dx_probe, frame_in is passed in uninitialized.
So we should set frame->bh to NULL in the beginning of while, not
the end. Otherwise, the first "goto fail2" will try to brelse(frame->bh)
while frame->bh is still invalid.

There's a "frame->bh = NULL" statement at the very beginning of
dx_probe().   Shouldn't that do the trick?
