blk-zoned: implement REQ_OP_ZONE_RESET_ALL
This implements REQ_OP_ZONE_RESET_ALL as a special case of the block device zone reset operations where we just simply issue bio with the newly introduced req op. We issue this req op when the number of sectors is equal to the device's partition's number of sectors and device has no partitions. We also add support so that blk_op_str() can print the new reset-all zone operation. This patch also adds a generic make request check for newly introduced REQ_OP_ZONE_RESET_ALL req_opf. We simply return error when queue is zoned and reset-all flag is not set for REQ_OP_ZONE_RESET_ALL.
