Subject: udptl: Ensure fec[] in udptl_build_packet() is initialized.
X-Git-Tag: 1.8.10.1~11

udptl: Ensure fec[] in udptl_build_packet() is initialized.

Scan results indicated that this array could be used uninitialized.  At a quick
look, it looks correct.  In any case, initializing it is a Good Thing (tm).
