[PATCH -next] device-dax: make dev_dax_kmem_probe() static

[Wei Yongjun <weiyongjun1@huawei.com>]

sparse report warning as follows:

drivers/dax/kmem.c:22:5: warning:
 symbol 'dev_dax_kmem_probe' was not declared. Should it be static?

dev_dax_kmem_probe() is not used outside of kmem.c, so marks
it static.
