Be more defensive towards malicious USB devices

This avoids potential panics due to 0-sized memory allocation attempts,
which could be triggered by malicious USB devices.

Tested on NetBSD/amd64 with a Sony Xperia X (SailfishOS).

Based on an initial patch by Nick Hudson <skrll@NetBSD.org>, thanks!

Fixes PR kern/52383.
