Subject: scsi: hisi_sas: Make sg_tablesize consistent value
Patch-mainline: v5.0-rc1
Git-commit: 6db831f4ef764ca19d7300d56ab9455af3cb930d
References: FATE#326253
Sht->sg_tablesize is set in the driver, and it will be assigned to
shost->sg_tablesize in SCSI mid-layer. So it is not necessary to assign
shost->sg_table one more time in the driver.
In addition to the change, change each scsi_host_template.sg_tablesize
to HISI_SAS_SGE_PAGE_CNT instead of SG_ALL.
