bdev/fio_plugin: add support for --initial_zone_reset

Browse Source 
--initial_zone_reset has to be done before fio creates its threads.
Since --zonemode=zbd only supports --create_serialize=1 (default),
this is possible.

Since this requires an I/O channel, and is called before threads
are created, follow the same pattern as spdk_fio_report_zones()
and simply initialize the thread early if this option is used.

Just like spdk_fio_report_zones(), thread cleanup has to be
called explicitly in case of error. (Since fio will only call
.cleanup() on threads that it has called .init() on.)
