perf hists: Return error from hists__collapse_resort()

Browse source

Currently hists__collapse_resort() and hists__collapse_insert_entry()
don't return an error code. Now that callchain_merge() can check for
errors, abort and pass the error to the user.  A later patch can add
more work which also can fail.
