arm/boot: Free dtb blob memory after use

The dtb blob returned by load_device_tree() is in memory allocated
with g_malloc(). Free it accordingly once we have copied its
contents into the guest memory. To make this easy, we need also to
clean up the error handling in load_dtb() so that we consistently
handle errors in the same way (by printing a message and then
returning -1, rather than either plowing on or exiting immediately).
