sctp: remove unnecessary NULL check in sctp_association_init()

Browse Source 
'&asoc->ulpq' passed to sctp_ulpq_init() as the first argument,
then sctp_qlpq_init() initializes it and eventually returns the
address of the struct member back. Therefore, in this case, the
return pointer cannot be NULL.

Moreover, it seems sctp_ulpq_init() has always been used only in
sctp_association_init(), so there's really no need to return ulpq
anymore.

Detected using the static analysis tool - Svace.
