scsi: sr: Sanity check returned mode data
commit a00a7862513089f17209b732f230922f1942e0b9 upstream.
Kefeng Wang discovered that old versions of the QEMU CD driver would
return mangled mode data causing us to walk off the end of the buffer in
an attempt to parse it. Sanity check the returned mode sense data.
