kernel - Change lwkt_wait_ipiq() to use the TSC
* lwkt_wait_ipiq() was using a static counter/constant for its failsafe
panic, which can vary immensly over time and might not be long enough
for systems running under VMs.
* Change the code to use the TSC api to properly time the failsafe. It
will generate warnings each second and panic at 10 seconds if the IPIQ
fails to drain.
