shell: Test for surface->width == 0 to see if input-panel was unmapped

The input-panel codes tries to see determine if a buffer has not yet
been attached (or a NULL buffer has been attached), and doesn't map
the input panel surface yet in that case.  However, it test for
buffer_ref being NULL, which can happen for other reasons.  The right
test is to see if surface->width is 0, which means that either a
buffer hasn't yet been attached or a NULL buffer has been attached.
