gnuradio-runtime : Fix uninitialized variable.

Addresses Coverity 1043304. If either deserialize_untagged fails, goto the
error handler. Original code probably worked, since if one call failed, the
other would.

gr-fec : Fix uninitialized variable error.

Addresses Coverity issue 1043258. Code likely worked since d_count is only
used with the % operator. I think there is a potential rollover bug in the
code and the use of % is a performance issue. This code needs some more
janitor work.
