bgpd: Fix coverity SA issue with copying over prefix data

in bgp_nlri_parse_ip there is a `sanity` check to ensure
that the prefix length as specified by the packet
will fit inside of a `struct prefix` correctly.  The problem
here of course is that this is only v4 / v6 unicast/multicast
parsing and the bytes will never be more than 16, but we are copying
into a part of the struct prefix that is only 16 bytes, but with
this check the length may be up to 47 bytes( but not really possible ).

Limit the size check to at most 16 bytes (since we are only handling
v4 or v6 addresses here )
