qemu-ga: execute fsfreeze-freeze in reverse order of mounts
Currently, fsfreeze-freeze may cause deadlock if a guest has loopback mounts
of image files in its disk; e.g.:
# mount | grep ^/
/dev/vda1 / type ext4 (rw,noatime,seclabel,data=ordered)
/tmp/disk.img on /mnt type ext4 (rw,relatime,seclabel)
To avoid the deadlock, this freezes filesystems in reverse order of mounts.
