6lowpan: fix udp compress ordering
In case ((ntohs(uh->source) & LOWPAN_NHC_UDP_8BIT_MASK) the order of
uncompression is wrong. It's always first source port then destination
port as second.
See:
http://tools.ietf.org/html/rfc6282#section-4.3.3
"Fields carried in-line (in part or in whole) appear in the same order
as they do in the UDP header format"
