Implement callbacks needed for fio --zonemode=zbd, so that we can use fio
to exercise the bdev-zone layer in SPDK.
spdk_fio_report_zones() will be called before SPDK normally initializes
the threads.
spdk_fio_report_zones() simply initializes its spdk thread when called.
Threads not running against a zoned block device are not affected.
Each spdk thread is still destroyed after the fio run has completed,
as normal. If spdk_fio_report_zones() encounters an error, we have
to call spdk_fio_cleanup() so that the thread is added to the global
list of spdk threads that are cleaned up after main loop exit.
