History
Justin Hammond 62a7507427 drivers/usbhost: Check for the device before allocating an endpoint. 
A root hub port whose enumeration failed is enumerated again, and the slot
the failed attempt used has been given back by then, so the port has no
device context behind it.  xhci_epalloc() took that pointer and wrote the
new endpoint through it without looking, so the retry stored through NULL
and took the system down in answer to a device that had merely failed to
come up.

Check for the device, and free the endpoint that has no home rather than
leaking it.
