perf c2c: Free format list entries when c2c_hists__init() fails

Browse source

When c2c_hists__init() fails partway through hpp_list__parse(),
dynamically allocated format structures that were already added to
hists->list are leaked because he__get_c2c_hists() frees the hists
container without first unregistering the format entries.

Call perf_hpp__reset_output_field() before freeing the hists container
on the error path, matching what c2c_he_free() already does on the
normal destruction path.
