scsi: esas2r: remove initialization / cleanup dead wood
esas2r has been converted to hotplug style initialization long ago, but kept various remant of the old-style scsi_module.c initialization around. Remove those. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
