[PATCH] include/asm-generic/topology.h: remove dead code cpumask_of_node macro

[sunying]

From: Ying Sun <sunying@xxxxxxxxxxxxxx>

The macro of “cpumask_of_node(node)” in line 49 is a dead code
which will never be implemented，because its conditions of
line 30 "#ifndef CONFIG_NUMA" and line 48 "#ifdef CONFIG_NUMA"
are mutually exclusive. It is recommended to delete redundant code.

Suggested-by: Yanjie Ren <renyanjie01@xxxxxxxxx>
Signed-off-by: Ying Sun <sunying@xxxxxxxxxxxxxx>
