[PATCH] USB HID: add blacklist entry for HP keyboard

My earlier experiment (adding a clear-halt for the interrupt-in
endpoint)  failed.  It turns out that it does cause problems for other
devices.  And it wasn't needed anyway; a simple blacklist entry was
enough to get my HP keyboard working.

This patch (as643) removes the clear-halt call and adds the blacklist
entry.
