Remove erroneous DCHECK from KeyEventTracker
Remove erroneous DCHECK from KeyEventTracker

Remove DCHECK from KeyEventTracker's destructor that erroneously 
asserted that the pressed_keys_ set had to be empty before the plugin 
shutdowns. This DCHECK would fire under valid conditions, e.g. if one 
would close the browser window while holding down a key.
