Christof Schmitt 175b79f063 zfcp: Report scatter gather limit for DIX protection information
When sending DIX integrity segments with an I/O request, the
restriction for the maximum number of segments is still the same for
the zfcp hardware. Report the new sg_prot_tablesize for the SCSI host,
so that the number of integrity segments plus the number of data
segments is not larger than the hardware limit. This results in using
half of the hardware segments for integrity data and the other half
for regular data.
