Subject[PATCH v4 3/5] scsi: hisi_sas: Make sg_tablesize consistent value
Date
From: Xiang Chen <chenxiang66@hisilicon.com>

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.
