Documentation: fix sctp_wmem in ip-sysctl.rst
[ Upstream commit aa709da0e032cee7c202047ecd75f437bb0126ed ]
Since commit 1033990ac5b2 ("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.
Fixes: 1033990ac5b2 ("sctp: implement memory accounting on tx path")
