jtag/tcl: Fix double free in jtag newtap argument parsing

Found when grepping for void* casts. I'm pretty sure there are about
*picking a number out of the blue* 0.31 bugs per pointer cast in OpenOCD.

Verified by valgrind, i.e.:
valgrind openocd -f interface/jtagkey.cfg -c "jtag newtap dummy cpu -irlen foo"
