[SCSI] sr: fix test unit ready responses
Commit 210ba1d1724f5c4ed87a2ab1a21ca861a915f734 updated sr.c to use the scsi_test_unit_ready() function. Unfortunately, this has the wrong characteristic of eating NOT_READY returns which sr.c relies on for tray status. Fix by rolling an internal sr_test_unit_ready() that doesn't do this.
