include/linux/gfp.h: fix ___GFP_NOLOCKDEP value

Igor Stoppa has noticed that __GFP_NOLOCKDEP can use a lower bit. At the time commit 7e78442 ("lockdep: allow to disable reclaim lockup detection") was written we still had __GFP_OTHER_NODE but I have removed it in commit 41b6167 ("mm: get rid of __GFP_OTHER_NODE") and forgot to lower the bit value. The current value is outside of __GFP_BITS_SHIFT so it cannot be used actually.
