We have a union and a type both named after mips_instruction,
rust bindgen is not happy with this kind of naming alias.
Given that union mips_instruction is a part of UAPI, the best
thing we can do is to rename mips_instruction type.
Rename it as mips_insn, which is not conflicting with anything
and aligned with struct name here.
