mount_service: don't pass the chopped buffer to apply_fsconfig_mount_opts

Browse Source 
If mount_service_handle_mntopts_cmd previously looked at the mount
options to screen for allow_{other,root}, then tokstr (aka oc->value)
has been modified and not put back.  This causes truncation of the mount
options passed to fsconfig, so let's use the snapshot that we took
previously.  Codex noticed this.
