block: apply the segment size to the integrity buffer
The integrity buffer is a single segment and must not exceed
max_segment_size. max_integrity_io_size() applies that limit to the data
size instead, which is off by a factor of 64 for 8 bytes of PI per 512
bytes of data. A SCSI host that doesn't set a maximum segment size gets
64KiB, lpfc and qla2xxx among them, so a DIX disk behind one of those
does no IO above 64KiB.
Limit the buffer and derive the data size from that, which makes it 4MiB
for that case.
