kernel32/tests: do not compare handle with zero directly (Smatch)

[Michael Stefaniuc]

Andre,

this is actually a false positive in the file_handles Smatch script. Or 
a valid bug requiring an other solution; depending on the point of view.

file is used as a HFILE before this line and should be checked against 
INVALID_HANDLE_VALUE and not NULL.

file is now a normal HANDLE and should be checked against NULL.

This is ok.

The real fix is either for me to mark it as a false positives.
Or to make file a HFILE and use an other HANDLE variable for the mmap.
