[0/2,4.19.y] ALSA: usb-audio: sanity checks for pipes

Message

Backporting the sanity checks on pipes seems like a good idea.  These
are basically the same as Takashi Iwai's patches upstream.  The
difference is that upstream added two sanity checks to code that
doesn't exist in 4.19.

I had talked about backporting fcc2cc1f3561 ("USB: move
snd_usb_pipe_sanity_check into the USB core") but that's just a
refactor and not a bug fix.
