sctp: not allow to set asoc prsctp_enable by sockopt
As rfc7496#section4.5 says about SCTP_PR_SUPPORTED:
This socket option allows the enabling or disabling of the
negotiation of PR-SCTP support for future associations. For existing
associations, it allows one to query whether or not PR-SCTP support
was negotiated on a particular association.
It means only sctp sock's prsctp_enable can be set.
Note that for the limitation of SCTP_{CURRENT|ALL}_ASSOC, we will
add it when introducing SCTP_{FUTURE|CURRENT|ALL}_ASSOC for linux
sctp in another patchset.
v1->v2:
- drop the params.assoc_id check as Neil suggested.
Fixes: 28aa4c26fce2 ("sctp: add SCTP_PR_SUPPORTED on sctp sockopt")
