perf ui hists: Guard against NULL hist_entry in add_script_opt()

Browse source

In add_script_opt(), when the browser selection has no valid hist_entry
(for example, when all entries are filtered out or the trace is empty),
hist_browser__selected_entry() returns NULL.

Add an explicit check for he == NULL prior to accessing he->time to avoid a
potential NULL pointer dereference crash.
