RISC-V: KVM: Prevent HGATP_MODE_BARE passed
Current kvm_riscv_gstage_mode_detect() assumes H-extension must
have HGATP_MODE_SV39X4/SV32X4 at least, but the spec allows
H-extension with HGATP_MODE_BARE alone. The KVM depends on
!HGATP_MODE_BARE at least, so enhance the gstage-mode-detect
to block HGATP_MODE_BARE.
Move gstage-mode-check closer to gstage-mode-detect to prevent
unnecessary init.
