[PATCH] nvme: set BLK_FEAT_ZONED for ZNS multipath disks

[Christoph Hellwig]

The new stricter limits validation doesn't like a max_append_sectors value
to be set without BLK_FEAT_ZONED.  Set it before allocation the disk to
fix this instead of just inheriting it later.

Fixes: d690cb8ae14b ("block: add an API to atomically update queue limits")
