MIPS: Fix potential build failures using cpu_vpe_id on non-MT
When used in a non-MT kernel, the cpu_vpe_id macro never made use of
its cpuinfo argument. It doesn't actually need to since it is returning
a constant 0. However not using the argument can lead to build failures
if the compiler then notices that a variable used as part of the
argument is unused. Prevent that problem by "using" the argument as far
as the compiler is concerned, whilst still returning 0 as before.
