media: media.h: Fix shifting signed 32-bit value by 31 bits problem
Fix MEDIA_ENT_ID_FLAG_NEXT to use "U" cast to avoid shifting signed
32-bit value by 31 bits problem. This isn't a problem for kernel builds
with gcc.
This could be problem since this header is part of public API which
could be included for builds using compilers that don't handle this
condition safely resulting in undefined behavior.
