[v2,06/22] libtracefs: Free dynamic event list in utest

From: "Steven Rostedt (Google)" <[e-mail]>

When adding the tests for the tracefs_kprobe_destroy() API, the call to
get_dynevents_check() did not save the results and free it. This check can
only be ignored if the expected result is zero (passed in as the second
parameter), as in that case, the return would be NULL.

Fixes: 18ede68f ("libtracefs: Add tracefs_kprobe_destory() API")
