Subject: [PATCH] input: Remove invalid bug checks.

Commit 2f1aedcaed8fd99b823d451bf1fb02330c078f67 added several bug checks. Some
of them are not correct.

Checks in Init(Ptr|String|Bell|Led|Integer)FeedbackClassDeviceStruct verify
that no feedback struct was set yet, but that is not required. If any feedback
structs are already present, the function will chain them behind the new one.
