net: core: Pass the actual LL proto for DGRAM packet sockets

Browse source 
After L2 processing, the LL protocol type is already known and should be
set accordingly on the packet. Therefore it can be passed to the
net_packet_socket_input() function to allow proper socket filtering
based on protocol.

Additionally, as LL protocol type is 16 bit value, fix the proto
parameter type in net_packet_socket_input().
