In preparation for allowing BIO based device drivers to use zone write plugging and its zone append emulation, allow these drivers to call blk_revalidate_disk_zones() so that all zone resources necessary to zone write plugging can be initialized. To do so, remove the check in blk_revalidate_disk_zones() restricting the use of this function to mq request-based drivers to allow also BIO-based drivers to use it. This is safe to do as long as the BIO-based block device queue is already setup and usable, as it should, and can be safely frozen. The zone write plug hash table and conventional zone bitmap are allocated and initialized only for mq devices and for BIO-based devices that require zone append emulation.
