sd-id128: avoid an unnecessary function call in inline helper

Browse source 
When optimizing, the compiler will most likely replace the call to memcmp(),
but at -O0, the code that is emitted builds the call preamble and does the
call. Let's use the same pattern as with sd_id128_is_null() and
sd_id128_is_allf() and avoid the call.
