pd: fix transmit bug, add back in retry mechanism
Fix bug in pd transmission. The retry mechanism was not working right
and was causing us to not do any retries.
BUG=none
BRANCH=none
TEST=Test with a zinger unplugged from the wall. Samus sends source
cap and doesn't get a response. Verify on console printout that we
retried 3 times.
