virtio_blk: Fix default logical block size fallback

If we fail to read a logical block size in virtblk_read_limits() ->
virtio_cread_feature(), then we default to what is in
lim->logical_block_size, but that would be 0.

We can deal with lim->logical_block_size = 0 later in the
blk_mq_alloc_disk(), but the code in virtblk_read_limits() needs a proper
default, so give a default of SECTOR_SIZE.

Fixes: 27e32cd23fed ("block: pass a queue_limits argument to blk_mq_alloc_disk")
