rG8d5fef85f007: ietp(4): Load dummy HID report descriptor if mangled
Summary

Some Elantech trackpads have a mangled HID report descriptor, which reads
as having an incorrect input size (i.e. < IETP_REPORT_LEN_LO).
If the input size is incorrect, load a dummy report descriptor.

This was opened as an issue at https://github.com/wulf7/iichid/issues/64

Test Plan

Tested on an Asus C300 Chromebook.
