Xin Long 912964eacb sctp: check af before verify address in sctp_addr_id2transport 
Commit 6f29a13061 ("sctp: sctp_addr_id2transport should verify the
addr before looking up assoc") invoked sctp_verify_addr to verify the
addr.

But it didn't check af variable beforehand, once users pass an address
with family = 0 through sockopt, sctp_get_af_specific will return NULL
and NULL pointer dereference will be caused by af->sockaddr_len.

This patch is to fix it by returning NULL if af variable is NULL.

Fixes: 6f29a13061 ("sctp: sctp_addr_id2transport should verify the addr before looking up assoc")
