[PATCH] 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.
