[PATCH 02/12] x86/CPU/AMD: use correct format characters

From: Bill Wendling <redacted>

When compiling with -Wformat, clang emits the following warnings:

arch/x86/kernel/cpu/mce/amd.c:1119:67: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
        err = kobject_init_and_add(&b->kobj, &threshold_ktype, tb->kobj, get_name(cpu, bank, b));
                                                                         ^~~~~~~~~~~~~~~~~~~~~~

        err = kobject_add(&b->blocks->kobj, b->kobj, b->blocks->kobj.name);
                                                     ^~~~~~~~~~~~~~~~~~~~

                                                       ^~~~~~~~~~~~~~

                                                               ^~~~
                                                               "%s",

Use a string literal for the format string.
