map: fix ip4-map-t DF behavior

ip4_is_fragment(header)
or ip4_is_first_fragment(header) didn't changed
when packet with fragmentation needed arrives.

This patch checks DF flag and MTU with packet
length and if DF is set and length > MTU, packet
is dropped. In case if ignore_df is set, DF flag
makes no sense.

Type: fix
Fixes: d6d50cebde647f9a5ee7251a7fef977506f315d7
