[PATCH v3 1/2] RISC-V: KVM: Fix privilege mode setting in kvm_riscv_vcpu_trap_redirect()

[Anup Patel]

The kvm_riscv_vcpu_trap_redirect() should set guest privilege mode
to supervisor mode because guest traps/interrupts are always handled
in virtual supervisor mode.

Fixes: 9f7013265112 ("RISC-V: KVM: Handle MMIO exits for VCPU")
