[SCSI] lpfc: Set max_sectors in host template

Add max_sectors to the driver host template and initialize it with
0xFFFF since the driver has no limitations on the size a transfer
contained by a scsi command and that fits within the sg_tablesize
provisioned by the driver.  This fixes a performance issue seen in
some configurations.
