3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roger Quadros <rog...@ti.com>
commit e5bfeab0ad515b4f6df39fe716603e9dc6d3dfd0 upstream.
For whatever reason if XHCI died in the previous instant
then it will never recover on the next xhci_start unless we
clear the DYING flag.
