[PATCH 2/4] quartz/filesource: Check for past EOF read in _Request().

[Paul Gofman]

On Vista+ ReadFile() returns FALSE and sets ERROR_IO_PENDING even if the
requested read results in ERROR_HANDLE_EOF. This change fixes
filesource test with Wine quartz.dll on Windows and avoids regression
otherwise triggered by the next patch.
