block: set default max segment size in case of virt_boundary
For devices with virt_boundary limit, the driver may provide zero max
segment size, we have to set it as UINT_MAX at default. Otherwise, it
may cause warning in driver when handling sglist.
Fix it by setting default max segment size as UINT_MAX.
