mm/shuffle: convert module_param_call to module_param_cb 

JIRA: https://issues.redhat.com/browse/RHEL-1848

    mm/shuffle: convert module_param_call to module_param_cb

    module_param_call is now completely consistent with module_param_cb, so
    there is no need to keep two macros.  Convert module_param_call to
    module_param_cb since former is obsolete and latter is more kernel-ish.
