CVE-2011-1771 kernel: cifs oops when creating file with O_DIRECT set

CIFS does not do O_DIRECT, so when you open a file with it, you will trigger a NULL pointer dereference. This is a regression introduced with the patchset to clean up filehandle management in CIFS. The fix checks for a NULL filp->private_data before trying to dereference it.
