Evenly distribute the taskq threads across available CPUs
The problem is described in commit aeeb4e0c0ae75b99ebbaa3056f0afc8e12949532.
However, instead of disabling the binding to CPU altogether we just keep the
last CPU index across calls to taskq_create() and thus achieve even
distribution of the taskq threads across all available CPUs.
The implementation based on assumption that task queues initialization
performed in serial manner.
