xhci: Bigendian fix for skip_isoc_td()
Commit 926008c9386dde09b015753b6681c502177baa30 "USB: xhci: simplify logic of skipping missed isoc TDs" added a small endian bug. This patch fixes skip_isoc_td() to read the DMA pointer correctly. Signed-off-by: Matt Evans <matt@ozlabs.org> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
