scsi: lpfc: Use unsigned type for num_sge
LUNs going into "failed ready running" state observed on >1T and on even
numbers of size (2T, 4T, 6T, 8T and 10T). The issue occurs when DIF is
enabled at the host.
The kernel logs:
Cannot setup S/G List for HBAIO segs 1/1 SGL 512 SCSI 256: 3 0
The host lpfc driver is failing to setup scatter/gather list (protection
data) for the I/Os.
The return type lpfc_bg_setup_sgl()/lpfc_bg_setup_sgl_prot() causes the
compiler to remove the most significant bit. Use an unsigned type instead.
