disabled modules remain in tmpfs between service restarts

Affects Hardy (not checked Intrepid).

/etc/init.d/linux-restricted-modules-common does nothing when stopped. As a result, if the user disables modules using DISABLED_MODULES in /etc/default/linux-restricted-modules-common and restarts LRM the previously built modules are still in the mounted tmpfs.

This prevents user-built drivers from being used.

lrm-manager should check for the existence of a disabled driver and remove it:

        if [ "$1" = "$module" ]; then
          CURRENT_MODULE_DISABLED="true"
          if [ -e /lib/modules/"$KVER"/volatile/$module.ko ]; then
            rm -f /lib/modules/"$KVER"/volatile/$module.ko
          fi
          if [ "$LIST" = "yes" ]; then
            echo "$module"
          fi
          break
        else
