flowtop: Remove unnecessary bug_on() and rework presenter_screen_init()

The screen pointer can never be NULL, since initscr() exits the process
in case of an error. Thus the bug_on() check can be omitted.

Also rework presenter_screen_init() - where initscr() is called - to
return the pointer.

This will also silence a Coverity scanner error (even though it isn't
actually one).
