block: Clear zone limits for a non-zoned stacked queue
Device mapper may create a non-zoned mapped device out of a zoned device
(e.g., the dm-zoned target). In such case, some queue limit such as the
max_zone_append_sectors and zone_write_granularity endup being non zero
values for a block device that is not zoned. Avoid this by clearing
these limits in blk_stack_limits() when the stacked zoned limit is
false.
Fixes: 3093a479727b ("block: inherit the zoned characteristics in blk_stack_limits")
