RISC-V: KVM: Handle software-check exits for VCPU
The extension Zicfiss/Zicfilp introduces a software-check exception
to the privilege architecture. Redirect this exception to VS mode
when VCPU enable Zicfiss/Zicfilp so the CFI violations in VU/VS could
be reported.
Also, update kvm_riscv_vcpu_trap_redirect() to forward the SPELP
state to the VS mode.
