hidclass.sys: Drop reports when length doesn't match their declaration. 

Based on a patch from Ivo Ivanov <logos128@gmail.com>.

Instead of using the descriptor input report length, which is the
maximum length of all input reports.

Tests show that the reports should be dropped, in non-polled mode, when
their length is invalid, but we were dropping too many of them.
