sctp: walk the list of asoc safely
[ Upstream commit ba59fb0273076637f0add4311faa990a5eec27c0 ]
In sctp_sendmesg(), when walking the list of endpoint associations, the
association can be dropped from the list, making the list corrupt.
Properly handle this by using list_for_each_entry_safe()
Fixes: 4910280503f3 ("sctp: add support for snd flag SCTP_SENDALL process in sendmsg")
