Prepare for removing procfs support from the SCSI core by removing
procfs support from the esas2r driver. I think it is safe to remove
/proc/scsi/esas2r/ATTOnode because I have not found any public source
code that uses this endpoint and also because the most recent change
from @attotech.com for the esas2r driver happened nine years ago
(October 2013).
