ffmpeg | branch: master | Ganesh Ajjanagadde <gajjanagadde at gmail.com> | Sat Sep 19 17:37:14 2015 -0400| [6ea457f76d9771e5669305ac71e3f436ad4f6dfc] | committer: Michael Niedermayer

avformat/format: silence -Wdiscarded-qualifiers

lpd.buf is non-const and discards the const qualifier of zerobuffer.
This fixes -Wdiscarded-qualifiers observed with a variety of compilers, including GCC 5.2.
Note that this does not change the type of zerobuffer, and merely makes the intent explicit.
