net: page_pool: avoid touching slow on the fastpath
To fully benefit from previous commit add one byte of state
in the first cache line recording if we need to look at
the slow part.
The packing isn't all that impressive right now, we create
a 7B hole. I'm expecting Olek's rework will reshuffle this,
anyway.
