[SCSI] megaraid_sas: fix extended timeout handling
Replace the eh_timed_out method usage with setting sdev->timeout in slave_configure. Also only use the extended timeout for raid volumes, physical devices shouldn't need it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
