Subject: sctp: fix strchange_flags name for Stream Change Event
Git-commit: fd82d61ba142f0b83463e47064bf5460aac57b6e
Patch-mainline: v4.20-rc2
References: networking-stable-18_11_21

As defined in rfc6525#section-6.1.3, SCTP_STREAM_CHANGE_DENIED
and SCTP_STREAM_CHANGE_FAILED should be used instead of
SCTP_ASSOC_CHANGE_DENIED and SCTP_ASSOC_CHANGE_FAILED.

To keep the compatibility, fix it by adding two macros.

Fixes: b444153fb5a6 ("sctp: add support for generating add stream change event notification")
