Close destroys the CrosUsbNotificationDelegate and vm_name
and guid args may be invalid after Close.

Removed HexEncode calls around guid.  I incorrectly added these earlier
when I was seeing garbage in the logs for guid and assumed it was binary.
I should have looked into this more at the time and realized that guid
was being deleted by the call to Close.
