ixgbe: fix unmap length bug
This patch addresses three WARN_ON statements from DMA-API debug code
ixgbe is mapping more than it unmaps, reduce the length of the map call and
remove the "used once" local variable.
found by Joerg Roedel <[email protected]> in 2.6.30, so is a candidate
for -stable.
in addition, fix missing ->dma = 0 after unmap to prevent double free with
pci_unmap_single
and lastly, don't unmap (half) pages that aren't mapped.
