monitor: Check whether TCG is enabled before running the "info jit" code

Browse Source 
The "info jit" command currently aborts on Mac OS X with the message
"qemu_mutex_lock: Invalid argument" when running with "-M accel=qtest".
We should only call into the TCG code here if TCG has really been
enabled and initialized.
