[PATCH] tracing: Fix error handling in event_trigger_parse

[Miaoqian Lin]

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

Fixes: e1f187d09e11 ("tracing: Have existing event_command.parse() 
implementations use helpers")
