commit 3feb9059c31a5c08ec2c2ef81de439b6dec4f101

libxl: don't add cache mode for qdisk cdrom drives
qemu commit 91a097e7 forbids specifying cache mode for empty
drives. Attempting to create a domain with an empty qdisk cdrom
drive results in
qemu-system-x86_64: -drive if=ide,index=1,readonly=on,media=cdrom,
cache=writeback,id=ide-832: Must specify either driver or file
libxl only allows an empty 'target=' for cdroms. By default, cdroms
are readonly (see the 'access' parameter in xl-disk-configuration.txt)
and forced to readonly by any tools (e.g. xl) using libxlutil's
xlu_disk_parse() function. With cdroms always marked readonly,
explicitly specifying the cache mode for cdrom drives can be dropped.
The drive's 'readonly=on' option can also be set unconditionally.
