[PATCH blktests 2/5] zbd/004: Add zone condition "Closed" for sequential write required zones

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

The test case zbd/004 executes write operations for two sequential write
required zones across the zone boundary between them. After the write
operation, the second zone has non-zero write pointer. At that status,
the zone can have not only "Implicit Open" condition but also "Closed"
condition based on zone status management logic of the block zoned device.

Add "Closed" condition to the zone condition check logic in zbd/004. Add
ZONE_COND_CLOSED constant definition in zbd/rc.
