The new generic_bug_clear_once() function fails to build when
modules are disabled:
lib/bug.c: In function 'generic_bug_clear_once':
lib/bug.c:213:32: error: 'module_bug_list' undeclared (first use in this function); did you mean 'module_sig_ok'?
list_for_each_entry_rcu(mod, &module_bug_list, bug_list)
This adds another #ifdef around the code that resets the counters
in modules.
Fixes: 371435f78e9e ("kernel debug: support resetting WARN_ONCE for all architectures")
