PATCH: GetTempFileName

[Marcus Meissner]

Hi,

If we were starting two programs in the same second which create
the same tempfiles, it would create files with the same filename
and the CreateFile() would return witth ERROR_SHARING_VIOLATION,
not ERROR_FILE_EXISTS.

This comes from EEXIST -> STATUS_OBJECT_NAME_COLLISION translation
in server/file.c which leads to ERROR_SHARING_VIOLATION in the end.

A better fix might to fix that error code translation chain.

Ciao, Marcus

Changelog:
	CreateFile returns ERROR_SHARING_VIOLATION for existing files
	currently.
