[PATCH -next] proc_fs: add stub for proc_mkdir_mode

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@oracle.com>

Provide a stub for proc_mkdir_mode() when CONFIG_PROC_FS is not
enabled, just like the stub for proc_mkdir().

Fixes this build error:
drivers/net/wireless/airo.c:4504: error: implicit declaration of function 'proc_mkdir_mode'
