reiserfs: Check if attrs are enabled for attr ioctls

 ReiserFS currently will allow the user to set/get attrs for files regardless
 if they are enabled. The patch checks to see if they are enabled, and returns
 -NOTTY if they are not.

 ext[23] doesn't need this check because attrs are always enabled.

 Please apply.
