[Xen-devel] [PATCH] fuzz/x86emul: remove bogus check against fuzzer msr index

[Wei Liu <wei.liu2@xxxxxxxxxx>]

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.
