Martin Elshuber faa47a0e03 gnrc_sixlowpan_iphc: Fixed encoding when COMP=0
Summary:

Even ehen COMP is cleared, the algorithm always elides part of the address when a matching
context is found.

This behviour occurs because in the line

  if ((src_ctx != NULL) || ipv6_addr_is_link_local(&(ipv6_hdr->src)))

the COMP bit is not tested.

This patch fixes the problem by setting [src|dst]_ctx to NULL if the
context must not be used.
