get_delay() undefined in loss detection pseudocode

[martinduke]

In draft-ietf-quic-recovery.md

` if (rto_count = 0):
alarm_duration = max(200ms, smoothed_rtt + 4 x rttvar);
else:
alarm_duration = loss_detection_alarm.get_delay() << 1;
rto_count++;

The return value of get_delay() is not defined anywhere in the document.

@ianswett, correct this if it isn't purely editorial.

It's editorial, as well as not defined. I'll fix it.
