[PATCH -next] device-dax: Make function 'dev_dax_kmem_probe' static

[Wei Yongjun]

Fixes the following sparse warning:

drivers/dax/kmem.c:17:5: warning:
 symbol 'dev_dax_kmem_probe' was not declared. Should it be static?

Fixes: c221c0b0308f ("device-dax: "Hotplug" persistent memory for use like normal RAM")
