mem: Add byte mask to Packet::checkFunctional

This patch changes the valid-bytes start/end to a proper byte
mask. With the changes in timing introduced in previous patches there
are more packets waiting in queues, and there are regressions using
the checker CPU failing due to non-contigous read data being found in
the various cache queues.

This patch also adds some more comments explaining what is going on,
and adds the fourth and missing case to Packet::checkFunctional.
