net/smc: hash socket only after full initialisation in smc_sk_init()

smc_sk_init() calls sk->sk_prot->hash(sk) before several fields are
fully initialised: clcsock_release_lock, the saved clcsk_* callbacks,
use_fallback/fallback_rsn, and conn.close_work.  Once hash() returns the
socket is visible to concurrent hash walkers, which can then observe
uninitialised state.

Move hash(sk) to the end of smc_sk_init() so the socket is published
only after it is fully constructed.
