x86/MCE: Fix build warning introduced by "x86: do not use print_symbol()"

The following commit:

  7b6061627eb8 ("x86: do not use print_symbol()")

... introduced a new build warning on 32-bit x86:

  arch/x86/kernel/cpu/mcheck/mce.c:237:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
      pr_cont("{%pS}", (void *)m->ip);
                       ^

Fix the type mismatch between the 'void *' expected by %pS and the mce->ip
field which is u64 by casting to long.
