5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit a0067dfcd9418fd3b0632bc59210d120d038a9c6 ]
The sctp_sf_eat_auth() function is supposed to return enum sctp_disposition values but if the call to sctp_ulpevent_make_authkey() fails, it returns -ENOMEM.
This results in calling BUG() inside the sctp_side_effects() function. Calling BUG() is an over reaction and not helpful. Call WARN_ON_ONCE() instead.
This code predates git.
