Documentation: fix sctp_wmem in ip-sysctl.rst



[ Upstream commit aa709da0e032cee7c202047ecd75f437bb0126ed ]

Since commit 1033990a ("sctp: implement memory accounting on tx path"),
SCTP has supported memory accounting on tx path where 'sctp_wmem' is used
by sk_wmem_schedule(). So we should fix the description for this option in
ip-sysctl.rst accordingly.

v1->v2:
  - Improve the description as Marcelo suggested.
