[PATCH blktests 5/5] zbd/002: Check write pointers only when zones have valid conditions

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

Per ZBC, ZAC and ZNS specifications, when zones have condition "read
only", "full" or "offline", the zones may not have valid write pointers.
In such a case, do not check validity of write pointers.
