net: ieee802154: 6lowpan: fix frag reassembly
commit f18fa5de5ba7f1d6650951502bb96a6e4715a948 upstream.
This patch initialize stack variables which are used in
frag_lowpan_compare_key to zero. In my case there are padding bytes in the
structures ieee802154_addr as well in frag_lowpan_compare_key. Otherwise
the key variable contains random bytes. The result is that a compare of
two keys by memcmp works incorrect.
