Xin Long 7133583693 sctp: check policy more carefully when getting pr status
When getting pr_assocstatus and pr_streamstatus by sctp_getsockopt,
it doesn't correctly process the case when policy is set with
SCTP_PR_SCTP_ALL | SCTP_PR_SCTP_MASK. It even causes a
slab-out-of-bounds in sctp_getsockopt_pr_streamstatus().

This patch fixes it by return -EINVAL for this case.

Fixes: 0ac1077e3a ("sctp: get pr_assoc and pr_stream all status with SCTP_PR_SCTP_ALL")
