When HCE(Host Controller Error) is set, it means an internal
error condition has been detected. Software needs to re-initialize
the HC, so add this check in xhci resume.

v2: Follow Sergey Shtylyov <s.shtylyov@omp.ru>'s comment.
v3: Add stable@vger.kernel.org for stable release.
v4: Refine the commit message.
v5: Add a debug log. Follow Mathias Nyman <mathias.nyman@linux.intel.com>'s comment.
v6: Fix the missing declaration for str.

Ended up modifying this patch a bit more than I first intended,
- don't print warning in hibernation case, only error.
- maybe using a lot of stack for a debug string isn't really needed.
- make sure we read the usbsts register before checking for the HCE bit.
Does the below work for you? If yes, and you agree I'll apply it instead

Hi Mathias,
Yes, your patch works for me, thanks!
Will you submit a new patch? or should I update to a new version?
