Subject: [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.
