RISC-V: KVM: Return correct code for hsm stop function
According to the SBI specification, the stop function can only return error code SBI_ERR_FAILED. However, currently it returns -EINVAL which will be mapped SBI_ERR_INVALID_PARAM. Return an linux error code that maps to SBI_ERR_FAILED i.e doesn't map to any other SBI error code. While EACCES is not the best error code to describe the situation, it is close enough and will be replaced with SBI error codes directly anyways.
