Subject[PATCH 3.2 083/107] usb: xhci: Clear XHCI_STATE_DYING on start
3.2.72-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@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.
