Masami Hiramatsu (Google) 36be97e9eb tracing/trigger: Fix to return error if failed to alloc snapshot 
commit 0958b33ef5a04ed91f61cef4760ac412080c4e08 upstream.

Fix register_snapshot_trigger() to return error code if it failed to
allocate a snapshot instead of 0 (success). Unless that, it will register
snapshot trigger without an error.

Fixes: 0bbe7f7199 ("tracing: Fix the race between registering 'snapshot' event trigger and triggering 'snapshot' operation")
