Log Message:
usbdi(9): Fix usbd_get_no_alts.

This incorrectly rejected the configuration as invalid if any
descriptor is not large enough to be interface descriptors.

Instead, it should reject the configuration only if any descriptor is
not large enough to be a _descriptor_, or if any interface-type
descriptor is not large enough to be an interface descriptor, but
skip over descriptors of other types even if they're smaller than
interface descriptors.

Candidate fix for PR kern/56762.
