Benjamin Herrenschmidt bd42580a42 pp_fifo: Fix full fifo losing all data on simultaneous push & pop 
The pp_fifo decides whether top = bottom means empty or full based
on whether the previous operation was a push or a pop.

If the fifo performs both in one cycle, it sets the previous op to
pop. That means that a full fifo being added a character and removed
one at the same time becomes empty.

Instead, just leave the previous op alone. If the fifo was empty, it
remains so, if it was full ditto.
