USB: Dealias -110 code (more complete)
The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.
