virnodedeviceobj: Don't unlock virNodeDeviceObj in virNodeDeviceObjListRemove()

Browse Source 
When virNodeDeviceObjListRemove() is called, the passed
virNodeDeviceObj is removed from internal list of node devices
and then unrefed and unlocked. While the former is warranted (the
object was refed at the beginning of the function) the unlock is
not. In fact, it's wrong from conceptual POV. We still want
threads working on the object tu mutually exclude each other.
