devdraw: fix dangling else 

Because of a dangling else, after adding a name to an image with 'N',
it was immediately deleted, resulting in Enoname in response to 'n'.

This went mostly unnoticed, since plan9port itself does not use named
images, but it can break external applications like truedraw[1].
