MIPS: KVM: Propagate kseg0/mapped tlb fault errors

Browse source

commit 9b731bcfde upstream.

Propagate errors from kvm_mips_handle_kseg0_tlb_fault() and
kvm_mips_handle_mapped_seg_tlb_fault(), usually triggering an internal
error since they normally indicate the guest accessed bad physical
memory or the commpage in an unexpected way.

Fixes: 858dd5d457 ("KVM/MIPS32: MMU/TLB operations for the Guest.")
Fixes: e685c689f3 ("KVM/MIPS32: Privileged instruction/target branch emulation.")
