avformat/vapoursynth: properly initialize err variable in read_header_vs()

The variable "err" is not initialized, and set only when something went wrong.
When everything is OK, nobody sets it, so using it result in UB.

libavcodec: Remove dynamic relocs from aarch64/h264idct_neon.S

Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
has code like:
        movrel          x14, X(ff_h264_idct_add_neon)

Linker cannot resolve them fully at link time and emits dynamic
relocations.
Use explicit labels instead so that no dynamic relocations are
needed at all.

Michael to implement this check and providing a sample that was
