perf c2c: Free format list entries when releasing c2c hist entries

Browse source

c2c_hists__init() calls hpp_list__parse() which allocates and registers
format entries on hists->list.  When c2c_he_free() destroys a c2c hist
entry, it deletes the histogram entries and frees the hists container but
never unregisters the format list entries, leaking them.

Call perf_hpp__reset_output_field() before freeing the hists to properly
unregister and free all format entries.
