We need to validate the number of pages consumed by data_len, otherwise frags
array could be overflowed by userspace. So this patch validate data_len and
return -EMSGSIZE when data_len may occupies more frags than MAX_SKB_FRAGS.

Applied and queued up for -stable.

Please do not add explicit stable CC:'s to networking patches, I queue
appropriate changes up myself, and submit them only when I feel that
the change has had sufficient exposure and testing in Linus's tree.

Sure, would pay attention next time.
