RISC-V: Add a non-void return for sbi v02 functions
SBI v0.2 functions can return an error code from SBI implementation. We are already processing the SBI error code and coverts it to the Linux error code. Propagate to the error code to the caller as well. As of now, kvm is the only user of these error codes.
