x86: Always inline task_size_max()

Browse Source 
Fix:

  vmlinux.o: warning: objtool: handle_bug()+0x10: call to task_size_max() leaves .noinstr.text section

When #UD isn't a BUG, we shouldn't violate noinstr (we'll still
probably die, but that's another story).

Fixes: 025768a966 ("x86/cpu: Use alternative to generate the TASK_SIZE_MAX constant")
