scsi: ses: Fix wrong page error

bjking1 · martinkpetersen · commit 424f727b9413 · 2017-08-08T11:49:52.000-04:00
If a SES device returns an error on a requested diagnostic page, we are
currently printing an error indicating the wrong page was received. Fix
this up to simply return a failure and only check the returned page when
the diagnostic page buffer was populated by the device.
