RISC-V: Allow hartid-to-cpuid function to fail.
It is perfectly okay to call riscv_hartid_to_cpuid for a hartid that is not mapped with an CPU id. It can happen if the calling functions retrieves the hartid from DT. However, that hartid was never brought online by the firmware or kernel for any reasons. No need to BUG() in the above case. A negative error return is sufficient and the calling function should check for the return value always.
