USB: Fix parsing of SuperSpeed Endpoint Companion descriptor.

usb_parse_ss_endpoint_companion() was supposed to allocate a structure to
hold the SuperSpeed Endpoint Companion descriptor, and either copy the
values the device returned, or fill in default values if the device
descriptor did not include the companion descriptor.

However, the previous code would miss the last endpoint in a configuration
with no descriptors after it.  Make usb_parse_endpoint() allocate the SS
endpoint companion descriptor and fill it with default values, even if
we've run out of buffer space in this configuration descriptor.
