udev-builtin-usb_id: guard against overflow when reading descriptor data

CID#996458. Coverity warns that we trust desc->bLength as read in
the input data to adjust our position in the buffer. This value could
be anything, leading to overflow. It's unlikely that the kernel feeds
us invalid data, but let's me more careful.

If any error is encountered, more logs are given.
