[2/2] shlwapi: Write file access also assumes read access.

[Dmitry Timoshkov]

Admittedly this is a CreateFile() bug which was hidden by ReadFile 0-length
read optimization, but that needs to be tested and fixed separately.
IStream_Read(stream, NULL, 0, &count) on a file created with SHCreateStreamOnFileEx(STGM_WRITE)
was failing because of this corner case.
