Set max_segment_size as UINT_MAX explicitly:
- storvrc uses virt_boundary to define `segment`
- strovrc does not define max_segment_size
So define max_segment_size as UINT_MAX, otherwise __blk_rq_map_sg() takes
default 64K max segment size and splits one virtual segment into two parts,
then breaks virt_boundary limit.
Before commit ec84ca4025c0 ("scsi: block: Remove now unused queue limits helpers"),
max segment size is set as UINT_MAX in case that virt_boundary is
defined.
