Fix LLVM/clang conversion errors (#2473)

This fixes some conversion errors one gets when compiling with
LLVM/clang. Most of them are caused when a bit-specific type (i.e.
`uint16_t`) is implicitly cast to an `enum` of smaller value range.

The fix is just an explicit casting of those types to the desired target
type.
