We had quite a few driver using the first alternate setting instead of
the current one when doing descriptor sanity checks. This is mostly an
issue on kernels with panic_on_warn set due to a WARN() in
usb_submit_urn(). Since we've started backporting such fixes (e.g. as
reported by syzbot), I've marked these for stable as well.
Included are also a couple of related clean ups to prevent future
issues.
