avcodec/{arm,neon}/mpegvideo: Readd a missed initialization
This was accidentally removed in
357fc5243c32300bba91c096488e86558beed4c8.
This fixes test failures when built with Clang and MSVC;
surprisingly, the checkasm test did seem to pass when built with
GCC. Clang and MSVC also warn about the use of the uninitialized
variable, while GCC didn't.
