Andreas Rheinhardt 9267e2ff0d avcodec/flashsv2enc: Fix use of uninitialized value ...

Before 257a83b969, certain buffers were
zero-allocated in the init function and only reallocated lateron if they
turned out to be too small; now they are only allocated during init,
leading to use-of-uninitialized values lateron. The same could happen
before if the dimensions are big enough so that the buffers would be
reallocated, as the new part of the reallocated buffer would not be
zeroed (happened for 960x960). So always zero the buffers in the
function designed to init them.
