perf probe-file: Delete namelist in del_events() on the error path
[ Upstream commit e0fa7ab42232e742dcb3de9f3c1f6127b5adc019 ]
ASan reports some memory leaks when running:
# perf test "42: BPF filter"
This second leak is caused by a strlist not being dellocated on error
inside probe_file__del_events.
This patch adds a goto label before the deallocation and makes the error
path jump to it.
