perf hists: Remove needless global col lenght calcs 

To support multiple events we need to do these calcs per 'struct hists'
instance, and it turns out we already do that at:

	__hists__add_entry
		hists__inc_nr_entries
			hists__calc_col_len

for all the unfiltered hist_entry instances we stash in the rb tree, so
trow away the dead code.
