KVM: x86: Handle emulation failure directly in kvm_task_switch()
Consolidate the reporting of emulation failure into kvm_task_switch() so that it can return EMULATE_USER_EXIT. This helps pave the way for removing EMULATE_FAIL altogether. This also fixes a theoretical bug where task switch interception could suppress an EMULATE_USER_EXIT return.
