Alec Berg d27dacf214 host_command_pd: loop over sending PD status host command ...

Modify host_command_pd.c to loop over sending of PD status
host command and processing the response as long as the
alert GPIO is active.

This fixes a potential bug that if the alert line is held
low for more than one PD status host command, then we would
not process the return status.

Also, fix a bug in which we could call alert() for a
non-existent port.

BUG=none
BRANCH=strago
TEST=verified on samus and glados. connected charger and verified
that we negotiate a contract and set appropriate input currnet limit.
