[advapi32/service #2] Don't rely blindly on type

[Paul Vriens]

Hi,

On Wine, type is unchanged in a failure case for RegQueryValueExW. This means
the previous code relied on the returned type of the previous last succeeded
call, huh?

I've checked on Windows and a failure case for RegQueryValueExW leads to a
random type on NT4, 0 on W2K/XP/W2K3 and an apparently fixed '92' on vista. So I
think we don't have to change our RegQueryValueExW for that.

Changed all the '||' into '&&' as that makes more sense. I will check on Windows
if there are any restrictions and change (or delete) the checks accordingly.

Changelog
     Don't rely blindly on type

Cheers,

Paul.
