afs: Fix SELinux setting security label on /afs
Make the AFS dynamic root superblock R/W so that SELinux can set the security label on it. Without this, upgrades to, say, the Fedora filesystem-afs RPM fail if afs is mounted on it because the SELinux label can't be (re-)applied. It might be better to make it possible to bypass the R/O check for LSM label application through setxattr.
