Johan Hovold 175f88a374 USB: lvstest: tighten endpoint sanity check
Use the new endpoint helpers to lookup the required interrupt-in
endpoint.

Note that this in fact both loosens and tightens the endpoint sanity
check by accepting any interface with an interrupt-in endpoint rather
than always using the first endpoint without verifying its type.

Use the new endpoint helpers to lookup the interrupt-in endpoint,
and only print the corresponding debugging information in case it is
found.

Note that the descriptors are searched in reverse order to avoid any
