scsi: lpfc: Set max DMA segment size to HBA supported SGE length

During I/O, the following warning message occasionally appears:

DMA-API: lpfc 0000:04:00.0: mapping sg segment longer than device claims to
support [len=131072] [max=65536]

The HBA is capable of supporting 131,072 bytes, so notify DMA layer via the
dma_set_max_seg_size() API during hba initialization.
