RISC-V: KVM: Introduce KVM_EXIT_FAIL_ENTRY_NO_VSFILE
Currently, we return CSR_HSTATUS as hardware_entry_failure_reason when
kvm_riscv_aia_alloc_hgei failed in KVM_DEV_RISCV_AIA_MODE_HWACCEL
mode, which is vague so it is better to return a well defined value
KVM_EXIT_FAIL_ENTRY_NO_VSFILE provided via uapi/asm/kvm.h.
