disable_pid_allocation only has a single caller, in kernel/pid_namespace.c, so when CONFIG_PID_NS=n we don't need it. I don't think we need to #ifdef the declaration away, since we'll just fail at link time rather than compile time, should disable_pid_allocation ever grow a caller outside pid_namespace.c.
