    RISC-V: KVM: Fix incorrect reg_subtype labels in kvm_riscv_vcpu_set_reg_isa_ext function
    
    [ Upstream commit c66f3b40b17d3dfc4b6abb5efde8e71c46971821 ]
    
    In the function kvm_riscv_vcpu_set_reg_isa_ext, the original code
    used incorrect reg_subtype labels KVM_REG_RISCV_SBI_MULTI_EN/DIS.
    These have been corrected to KVM_REG_RISCV_ISA_MULTI_EN/DIS respectively.
    Although they are numerically equivalent, the actual processing
    will not result in errors, but it may lead to ambiguous code semantics.
