Subject: scsi: hisi_sas: fix PI memory size
Git-commit: a14da7a20d499c54ebe53e430283e3bc17d3e89f
Patch-mainline: v4.18-rc1
References: FATE#326253
There are 28 bytes of protection information record of SSP for v3 hw, 16
bytes for v2 hw, and probably 24 for v1 hw (forgotten now).
So use a value big enough in hisi_sas_command_table_ssp.prot to cover
all cases.
