ALSA: usb-audio: Add skip_validation option
The unit descriptor validation may lead to a probe error when the
device provides a buggy descriptor or the validator detected
incorrectly. For identifying such an error and band-aiding, give a
new module option, skip_validation. With this option, the driver
ignores the validation errors with the hexdump of the unit
descriptor, so we can check it in a bit more details.
