sctp: get pr_assoc and pr_stream all status with SCTP_PR_SCTP_ALL instead

According to rfc7496 section 4.3 or 4.4:

   sprstat_policy:  This parameter indicates for which PR-SCTP policy
      the user wants the information.  It is an error to use
      SCTP_PR_SCTP_NONE in sprstat_policy.  If SCTP_PR_SCTP_ALL is used,
      the counters provided are aggregated over all supported policies.

We change to dump pr_assoc and pr_stream all status by SCTP_PR_SCTP_ALL
instead, and return error for SCTP_PR_SCTP_NONE, as it also said "It is
an error to use SCTP_PR_SCTP_NONE in sprstat_policy. "

Fixes: 826d253d57b1 ("sctp: add SCTP_PR_ASSOC_STATUS on sctp sockopt")
Fixes: d229d48d183f ("sctp: add SCTP_PR_STREAM_STATUS sockopt for prsctp")
