Tan Chi 41e81f7e3e RISC-V: KVM: Fix HSM hart status error propagation 
kvm_sbi_hsm_vcpu_get_status() returns SBI_ERR_INVALID_PARAM when
the requested hart does not exist. However, the HART_STATUS case
returns from the SBI handler without storing this error in
retdata->err_val.

As a result, a guest querying the status of a non-existent hart
observes SBI_SUCCESS instead of SBI_ERR_INVALID_PARAM.

Use the common SBI error handling path for HART_STATUS after
saving a valid hart state in retdata->out_val. This preserves
the returned error when kvm_sbi_hsm_vcpu_get_status() fails.
