top: fix a bug from when 'Ctrl' window was made sticky

In the patch referenced below the bottom 'Ctrl' window
was made to remain until it was dismissed by the user.

As such, it required abandoning a 'Cap_nl_clreos' used
when all the terminal rows had not been drawn. Instead
each line had to be cleared individually until the row
reserved for that 'Ctrl' window area had been reached.

Unfortunately, while a 'Cap_nl_clreos' didn't create a
problem for 'batch' mode, a 'Cap_clr_eol' used instead
yielded an unending loop if those rows were limitless.

So, now we will only clear that area when top isn't in
'batch' mode (which should have always been the case).
