virtio_blk_submit_multireq() fuses adjacent in-zone requests into a single request. On a zoned backend, a merged zone append request that straddles a zone boundary is rejected by the device because each write/read must stay within a single zone (virtio 1.4, 5.2.6.1). Add a bail condition to the merge coalescer: if combining the candidate request into the current batch would cross a zone boundary, flush the current batch and start a new one.
