Damien Le Moal b66f79b706 null_blk: Do not request ELEVATOR_F_ZBD_SEQ_WRITE elevator feature
With zone write plugging enabled at the block layer level, a zoned
device can only ever see at most a single write operation per zone.
There is thus no need to request a block scheduler with strick per-zone
sequential write ordering control through the ELEVATOR_F_ZBD_SEQ_WRITE
feature. Removing this allows using a zoned null_blk device with any
scheduler, including "none".
