libregexp: fix assert check for compile1 instruction count
the assert fails for regcompnl(".") as TANY is compiled to
one instruction instead of two when nl == 0.
its not a problem when we end up with less instructions, so
changing the assert condition from == to <= to make sure we
didnt overrun the buffer.
