[CIFS] fix oops in cifs_lookup during net boot
Fixes bugzilla.kernel.org bug number 14641
Lookup called during network boot (network root filesystem
for diskless workstation) has case where nd is null in
lookup. This patch fixes that in cifs_lookup.
(Shirish noted that 2.6.30 and 2.6.31 stable need the same check)
