[PATCH v2 0/3] t/zbd: Fix max_open_zones related failures

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

Recent changes in fio [1] triggered three failures in the test script
t/zbd/test-zoned-support. This series address the failures.

The first failure was caused by difference between max_open_zones value that fio
refers and that test script refers. The first patch modifies the test script to
use the value fio refers.

The second failure was observed when users specify special max_open_zones values
larger than the max_open_zones limit of the test target device. The second patch
adds --ignore_zone_limits option to the fio command only when users specify such
special conditions.

The third failure was caused by write target zone count bug in the test case 31.
Data write to more zones than max_open_zones limit resulted in exceeding
max_open_zones limit. The third patch fixes the write target zone count logic.
