RISC-V: Fix error code returned by riscv_hartid_to_cpuid()
[ Upstream commit 533b4f3a789d49574e7ae0f6ececed153f651f97 ]
We should return a negative error code upon failure in
riscv_hartid_to_cpuid() instead of NR_CPUS. This is also
aligned with all uses of riscv_hartid_to_cpuid() which
expect negative error code upon failure.
Fixes: 6825c7a80f18 ("RISC-V: Add logical CPU indexing for RISC-V")
Fixes: f99fb607fb2b ("RISC-V: Use Linux logical CPU number instead of hartid")
