scsi: fix buffer overflow in scsi_req_parse_cdb (CVE-2015-5158)
This is a guest-triggerable buffer overflow present in QEMU 2.2.0 and newer. scsi_cdb_length returns -1 as an error value, but the caller does not check it. Luckily, the massive overflow means that QEMU will just SIGSEGV, making the impact much smaller.
