Eric Dumazet 6ffc57ea00 af_packet: do not use READ_ONCE() in packet_bind() 
A recent patch added READ_ONCE() in packet_bind() and packet_bind_spkt()

This is better handled by reading pkt_sk(sk)->num later
in packet_do_bind() while appropriate lock is held.

READ_ONCE() in writers are often an evidence of something being wrong.
