[PATCH blktests v3 03/15] check: use set_conditions() for the CAN_BE_ZONED test cases

[Shin'ichiro Kawasaki]

When the test case with test() function is marked as CAN_BE_ZONED,
blktests runs the test case twice: once for non-zoned device, and the
second for zoned device. This is now implemented as a special logic in
the check script.

To simplify the implementation, use the feature to repeat test cases
with different conditions. Use set_conditions() and move out the special
logic from the check script to the common/zoned script file.
