I was assuming compiler will complain when assigning uint32_t to
uint16_t, but it seems '-Wconversion' compiler flag is required for this
warning.
Enabling this flag for DPDK build causes lots of warnings, I wonder if
we should add a new buildtype in meson that enables this flag.
And except from compiler warning, I think it is good to keep explicit
cast where assignment can cause change of value. This at worst can work
as documentation that assignment between different types done intentionally.
