Subject: [PATCH] KVM: selftests: Actually emit forced emulation prefix for kvm_asm_safe_fep()

Use KVM_ASM_SAFE_FEP, not simply KVM_ASM_SAFE, for kvm_asm_safe_fep(), as
the non-FEP version doesn't force emulation (stating the obvious).  Note,
there are currently no users of kvm_asm_safe_fep().

Fixes: ab3b6a7de8df ("KVM: selftests: Add a forced emulation variation of KVM_ASM_SAFE()")
