[PATCH v2 2/3] t/zbd: Add ignore_zone_limit option to test with special max_open_zones

[Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>]

Recent commit d2f442bc0bd5 ("ioengines: add get_max_open_zones zoned
block device operation") modified fio to compare --max_open_zones option
value and max_open_zones reported by the device. When the option
--max_open_zones is larger than the device limit, fio exits with an
error. However, sometimes it is useful to run fio with --max_open_zones
larger than the device limit to check performance impact of implicit
zone open and close by the zoned block devices. The test script
t/zbd/test-zbd-support has an option -o so that users can specify such
larger max_open_zones value. After the commit, such test runs fail with
the fio error.

To avoid the failure, modify the test script to specify another option
--ignore_zone_limits to fio command, which was added by the commit
575686bb85fa (zbd: add a new --ignore_zone_limits option). This option
is added to fio command only when users specify -o option and special
max_open_zones value to the test script. This change does not affect
default test conditions.
