I guess that's OK for development but I'm not convinced we need to
make this tunable for general end users.

I'm missing something here. The SRP initiator registers itself with
the SCSI midlayer after it has successfully connected to the target
port, so I don't see why it can't pass exactly the right sg_tablesize
value to the SCSI midlayer.
