avcodec/mpeg4videodec: Remove unnecessary ff_xvid_idct_init()

It is unnecessary: If the dst context is not already initialized,
then it will be initialized by memcpy(dst, src, sizeof(*dst),
which already initializes the IDCT to the desired one, potentially
followed by ff_mpv_common_init(), which does not touch the IDCT.

(This call has been added in f89d76c10355242c39b08f253c1d1524f45ef778;
the aforementioned copying took place back then, too, but
ff_mpv_common_init() reinitialized the IDCT to a non-xvid one,
therefore the initialization here has been added to fix
multithreaded decoding.)
