block: Fix null_blk_zoned creation failure with small number of zones
null_blk_zoned creation fails if the number of zones specified is equal to or is
smaller than 64 due to a memory allocation failure in blk_alloc_zones(). With
such a small number of zones, the required memory size for all zones descriptors
fits in a single page, and the page order for alloc_pages_node() is zero. Allow
this value in blk_alloc_zones() for the allocation to succeed.
Fixes: bf5054569653 "block: Introduce blk_revalidate_disk_zones()"
