staging:speakup:fix failure handling patch

[William Hubbs]

Hi Greg,

is it possible for this to go in before 2.6.37 is released?  This fixes
some error handling that would leave a virtual keyboard around when
speakup exits and also cleans up the error handling in our kobject code
in preparation for reworking that code to send uevents to user space so
we can remove the world writable bits and allow udev to change the
group on those files.

Thanks,

William
