Get the pin count from the Liberty cell not the Cell (#334) 

The Cell may come from LEF which doesn't have internal pins that
Liberty does.  This used to work by dumb luck where the extra two
power pins in LEF happened to align to the extra two internal pins
from Liberty.  With the change to pg_pins this no longer works.
