Subject: [PATCH v4 02/17] powerpc/ima: Drop unnecessary check for
 CONFIG_MODULE_SIG

When CONFIG_MODULE_SIG is disabled set_module_sig_enforced() is defined
as an empty stub, so the check is unnecessary.
The specific configuration option for set_module_sig_enforced() is
about to change and removing the check avoids some later churn.
