CPU id cannot be negative.

Making it unsigned also aligns with declarations in
include/asm-generic/numa.h used by arm64 and riscv and allows sharing
numa emulation code with these architectures.

Makes sense for both reasons. FWIW given how simple it is.

Maybe worth bringing a few more functions inline with this?
Probably something for another day given we don't care about the
inconsistency for this series.
