After the cleanup of swd and hla, there should be no more calls
to jtag_execute_queue() or to queue jtag commands if current
transport is not jtag. Thus we can start removing the jtag
specific code from adapters that do not support jtag.
To prevent some remaining call to jtag_execute_queue() to crash
openocd, verify the transport, print an error message if the
transport is not jtag, call the adapter's jtag_execute_queue()
only if it exist.
To identify code that still add commands in the jtag queue even
if transport is not jtag, print an error message in the function
jtag_queue_command(). For the moment, still queue the message,
even if will cause a memory leak if there is no following call
to jtag_execute_queue(); the target is to identify the issue and
cleanup the code, thus solving also the leak.
