[Click] ToUserDevice path

[Roman Chertov]

Hello,
    I just added a small patch to ToUserDevice.  The problem occurs when 
a script fails, because some element is not configured correctly.  Then, 
click-install bails and calls "cleanup" of ToUserDevice.  However, 
"configure" of ToUserDevice was never called, resulting in a soft 
lockup, as an uninitialized spin_lock is acquired.  I have made a small 
change in cleanup which will detect this situation and avoid the soft 
lockup.
