isl_printer_print_qpolynomial: drop special case for lone integer division
isl_printer_print_qpolynomial: drop special case for lone integer division

When this special case was introduced in 794007a
(isl_printer_print_qpolynomial: put parentheses around lone integer division,
Tue Sep 21 13:53:16 2010 +0200), an integer division was printer as
"[(aff)/d]" and could therefore be confused with a tuple.
Now, it is printed as "floor((aff/d)" and no such confusion
is possible any more.  Drop the now redundant special casing.
