    fuzz/x86emul: remove bogus check against fuzzer msr index
    
    The "reg" variable in fuzz_read_msr stores the real MSR index, not an
    index within the fuzzer.
    
    The rest of that function already handles things correctly. We just need
    to remove the bogus check.
    
    Spotted by Coverity.
