Ricardo Cañuelo b6aff6cd9b usb: hub: Guard against accesses to uninitialized BOS descriptors
commit f74a7afc224acd5e922c7a2e52244d891bbe44ee upstream.

Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h
access fields inside udev->bos without checking if it was allocated and
initialized. If usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:

Fall back to a default behavior if the BOS descriptor isn't accessible
and skip all the functionalities that depend on it: LPM support checks,
Super Speed capabilitiy checks, U1/U2 states setup.
