scsi: hisi_sas: Revert change to limit max hw sectors for v3 HW
Now that libsas and the SCSI core code limits the default sectors from
commit 4cbfca5f7750 ("scsi: scsi_transport_sas: cap shost opt_sectors
according to DMA optimal limit") and commit 608128d391fa ("scsi: sd: allow
max_sectors be capped at DMA optimal size limit"), there is no need for
the hack to limit the max HW sectors.
