sock: Make sk_protocol a 16-bit value
Match the 16-bit width of skbuff->protocol. Fills an 8-bit hole so
sizeof(struct sock) does not change.
Also take care of BPF field access for sk_type/sk_protocol. Both of them
are now outside the bitfield, so we can use load instructions without
further shifting/masking.
v5 -> v6:
- update eBPF accessors, too (Intel's kbuild test robot)
v2 -> v3:
- keep 'sk_type' 2 bytes aligned (Eric)
v1 -> v2:
- preserve sk_pacing_shift as bit field (Eric)
