[for-next][PATCH 28/31] tracing: Fix error handling in event_trigger_parse()

[Steven Rostedt]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

According to trigger_data_alloc() doc, trigger_data_free() should be
used to free an event_trigger_data object. This fixes a mismatch introduced
when kzalloc was replaced with trigger_data_alloc without updating
the corresponding deallocation calls.
