scsi: lpfc: Remove reftag check in DIF paths

Browse source

When preparing protection DIF I/O for DMA, the driver obtains reference
tags from scsi_prot_ref_tag().  Previously, there was a wrong assumption
that an all 0xffffffff value meant error and thus the driver failed the
I/O.  This patch removes the evaluation code and accepts whatever the upper
layer returns.
