[AF_PACKET]: Kill bogus CONFIG_PACKET_MULTICAST 

It is unconditionally set by af_packet.c, not by the Kconfig
subsystem, so just kill it off.

#define CONFIG_SOCK_PACKET 1
/*
Proposed replacement for SIOC{ADD,DEL}MULTI and
IFF_PROMISC, IFF_ALLMULTI flags.
It is more expensive, but I believe,
it is really correct solution: reentereble, safe and fault tolerant.
IFF_PROMISC/IFF_ALLMULTI/SIOC{ADD/DEL}MULTI are faked by keeping
reference count and global flag, so that real status is
(gflag|(count != 0)), so that we can use obsolete faulty interface
not harming clever users.
