[PATCH 6/7] alfred: gpsd: don't drop the rest of the answer for a bogus dataset

[Sven Eckelmann]

A dataset which is too short to even hold the length of the TPV string
aborted the processing of the answer. The positions of all following nodes
were dropped from the printed document although only the dataset of a
single node was malformed.

Skip such a dataset like the other bogus datasets instead.

Fixes: 2b901d69d8fb ("alfred: Add support for passing location information over 
alfred.")
