rust: kernel: cpu: mark `CpuId::current()` inline
When building the kernel using llvm-20.1.7-rust-1.89.0-x86_64,
this symbol is generated:
$ llvm-nm --demangle vmlinux | grep CpuId
ffffffff84c77450 T <kernel::cpu::CpuId>::current
However, this Rust symbol is a trivial wrapper around
`raw_smp_processor_id` function. It doesn't make sense
to go through a trivial wrapper for such functions,
so mark it inline.
After applying this patch, the above command will produce no output.
