Fix CopyData in Bind Mount

CopyData is an action which should be enabled only in mount volumes and images.

For example:
 [root@hostname]# pouch run  -it --name test2 -v /home/baijia.wr/volume/:/var/ docker.io/library/busybox:latest ls /var/
 spool  www
 [root@hostname]# ls /home/baijia.wr/volume/
 spool  www

Without this patch, data is copied form container's dir "/var/" to host's dir "/home/baijia.wr/volume/",
that is unexpected. So CopyData should be disabled in bind mount.
