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.
