tracepoint: Do not warn on ENOMEM
[ Upstream commit d66a270be3310d7aa132fec0cea77d3d32a0ff75 ]
Tracepoint should only warn when a kernel API user does not respect the
required preconditions (e.g. same tracepoint enabled twice, or called
to remove a tracepoint that does not exist).
Silence warning in out-of-memory conditions, given that the error is
returned to the caller.
This ensures that out-of-memory error-injection testing does not trigger
warnings in tracepoint.c, which were seen by syzbot.
