scsi: fix TUR error handling in sr_media_change() sr_test_unit_ready() returns 0 iff TUR succeeded - IOW, when media is present and the device is actually ready, so the return value wouldn't be zero when TUR ends with sense data. sr_media_change() incorrectly tests (retval || (scsi_sense_valid(sshdr)...)) when it tries to test whether TUR failed without sense data or with sense data indicating media-not-present. Fix the test using scsi_status_is_good() and update comments. - Fixed a comment typo spotted by Eike.
