Josh Durgin 99a3c89d5d rbd: make qemu's cache setting override any ceph setting 
To be safe, when cache=none is used ceph settings should not be able
to override it to turn on caching. This was previously possible with
rbd_cache=true in the rbd device configuration or a ceph configuration
file. Similarly, rbd settings could have turned off caching when qemu
requested it, although this would just be a performance problem.

Fix this by changing rbd's cache setting to match qemu after all other
ceph settings have been applied.
