Dan Carpenter b0604e2aac 6lowpan: Off by one handling ->nexthdr ...

[ Upstream commit f57c4bbf34 ]

NEXTHDR_MAX is 255.  What happens here is that we take a u8 value
"hdr->nexthdr" from the network and then look it up in
lowpan_nexthdr_nhcs[].  The problem is that if hdr->nexthdr is 0xff then
we read one element beyond the end of the array so the array needs to
be one element larger.
