net: sctp: sctp_auth_make_key_vector: use sctp_auth_create_key
In sctp_auth_make_key_vector, we allocate a temporary sctp_auth_bytes structure with kmalloc instead of the sctp_auth_create_key allocator. Change this to sctp_auth_create_key as it is the case everywhere else, so that we also can properly free it via sctp_auth_key_put. This makes it easier for future code changes in the structure and allocator itself, since a single API is consistently used for this purpose. Also, by using sctp_auth_create_key we're doing sanity checks over the arguments.
