[PATCH 9/9] coresight: perf: Add a missing call to etm_free_aux

[Mathieu Poirier]

From: Quentin Lambert <lambert.quentin@xxxxxxxxx>

Most error branches following the call to alloc_event_data contain a call
to etm_free_aux. This patch add a call to etm_free_aux to an error branch
that does not call it.

This issue was found with Hector.
