Subject: scsi: lpfc: Enlarge max_sectors in scsi host templates
Patch-mainline: v5.11-rc1
Git-commit: 7c30bb62ed5db15cdb59f5722122fbed7421641c
References: bsc#1164780
The driver supports arbitrarily large scatter-gather lists and the current
value for max_sectors is limiting.
Change max_sectors to the largest value. This was actually done prior but
it only corrected one template and that template was later removed.
So change the remaining 2 templates. Other areas which hard-set the sectors
value should be inheriting what is in the template.
