s3: Fix bug 8042: File creation on OS/X

With a case insensitive file system the stat cache lookup leaked the parent
directorys stat information from unix_convert into the smb_filename. This led
open_file_ntcreate to believe it just created a directory.

In the case where we do the search we already invalidate the stat struct.

Thanks to TAKAHASHI Motonobu for insisting! :-)
