TCPMv2: Print PRL states on higher level
TCPMv2: Print PRL states on higher level

This change moves the PRL state prints up to debug level 3.  This way,
debug level 2 can be used to easily just see incoming packets without
the state prints cluttering the EC console.

BRANCH=None
BUG=None
TEST=on drawlat, set "pd dump 2" and confirm responses are printed but
PRL states are not
