USB: Add expert info for unknown URBs captured by USBPcap
Current development builds and next official release of USBPcap will
feature generic unknown URB Function capture. When USBPcap notices URB
Function code that it does not understand, it'll write the USBPcap
pseudoheader with transfer type 0xFF (URB_UNKNOWN). The pseudoheader
will contain the IRP ID, status code, URB Function code, bus id, device
address and PDO->FDO or FDO->PDO flag. Other fields in the pseudoheader
will be 0.
Capturing such packets serves multiple purposes:
* Makes it clear that the USBPcap capture is incomplete
* Combined with expert info, makes casual users able to report device
whose driver does issue IRPs with unhandled URB Function codes
* Shows that USBPcap can be improved to capture such data
