sctp: fix an error code in sctp_sf_eat_auth()

[ Upstream commit 75e6def3b26736e7ff80639810098c9074229737 ]

The sctp_sf_eat_auth() function is supposed to enum sctp_disposition
values and returning a kernel error code will cause issues in the
caller.  Change -ENOMEM to SCTP_DISPOSITION_NOMEM.

Fixes: 65b07e5d0d09 ("[SCTP]: API updates to suport SCTP-AUTH extensions.")
