scsi: lpfc: fix calls to dma_set_mask_and_coherent()

The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA mask
value succeeded.  This resulted in NVMe/FC connections failing due to
corrupted data buffers, and various other SCSI/FCP I/O errors.
