ieee802154: 6lowpan: ensure of sending 1280 packets

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

This patch changes the 1281 MTU to 1280. Others stack have only a 1280
byte array for uncompressed 6LoWPAN packets, this avoid that these
stacks have an overflow. Sending 1281 uncompressed 6LoWPAN packets isn't
also rfc complaint.
