scsi: hisi_sas: Make sg_tablesize consistent value

Xiang Chen · martinkpetersen · commit 6db831f4ef76 · 2018-12-12T21:23:17.000-05:00
Sht-&gt;sg_tablesize is set in the driver, and it will be assigned to
shost-&gt;sg_tablesize in SCSI mid-layer. So it is not necessary to assign
shost-&gt;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.
