sctp: fix sockets_allocated imbalance after sk_clone()
sk_clone() increments sockets_allocated and sets the socket refcount to 2.
SCTP performs additional accounting in sctp_clone_sock(), so the clone-time
increment must be undone to avoid double counting.
Note we cannot simply remove the SCTP-side increment, because the SCTP
destroy path in sctp_destroy_sock() only decrements sockets_allocated when
sp->ep is set, which may not be true for all failure paths in
sctp_clone_sock().
Fixes: 16942cf4d3e3 ("sctp: Use sk_clone() in sctp_accept().")
