t/zbd: Remove write before random read/write from test case #17

The test case #17 writes data to the last zone before random read/write.
This avoided read failure when read is chosen for the first operation of
the random read and write. Such failure case was prevented by the commit
fb0259fb276a ("zbd: Ensure first I/O is write for random read/write to
sequential zones"). Then the write is no longer required. Remove it.
