[EXPAND] Free IFS state after here document expansion

Here's another bug bisecting to f42e443bb ([EXPAND] Fix
ifsfirst/ifslastp leak, 2010-09-08).  It was found with the following
test case, based on the configure script for Tracker:

	dash -x -c '
		<<-_ACEOF
		$@
		_ACEOF
		exec
	' - abcdefgh
	+
	+ exec   �a
	exec: 1: : Permission denied

The missing ifsfree call is in expandarg when it returns to openhere
during here document expansion.
