KVM: x86 emulator: fix X86EMUL_RETRY_INSTR and X86EMUL_CMPXCHG_FAILED values
Currently X86EMUL_PROPAGATE_FAULT, X86EMUL_RETRY_INSTR and X86EMUL_CMPXCHG_FAILED have the same value so caller cannot distinguish why function such as emulator_cmpxchg_emulated() (which can return both X86EMUL_PROPAGATE_FAULT and X86EMUL_CMPXCHG_FAILED) failed.
