Joe Damato 3cb430e62c net: bnxt: Use dma_unmap_len for TX completion unmapping
Store the DMA mapping length in each TX buffer descriptor via
dma_unmap_len_set at submit time, and use dma_unmap_len at completion
time.

This is a no-op for normal packets but prepares for software USO,
where header BDs set dma_unmap_len to 0 because the header buffer
is unmapped collectively rather than per-segment.
