nds32: Fix casesi (PR70668) 

Expanders do not have more elements in the operands array than declared
in the pattern.  So, we cannot use operands[5] here.  Instead just
declare and use another rtx.


	PR target/70668
	* config/nds32/nds32.md (casesi): Don't access the operands array
	out of bounds.
