This patch removes handling of LOWPAN_IPHC_DAM_00 inside the
lowpan_compress_addr_64 function. The case of LOWPAN_IPHC_DAM_00 can
never occur. there exists a if branch which use LOWPAN_IPHC_DAM_11 and
LOWPAN_IPHC_DAM_10 and inside the else branch LOWPAN_IPHC_DAM_01. So
LOWPAN_IPHC_DAM_00 can never occur.
