[PATCH -next] libnvdimm/security: Make symbol '__nvdimm_security_overwrite_query' static

['Wei Yongjun]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

The sparse tool complains as follows:

drivers/nvdimm/security.c:416:6: warning:
 symbol '__nvdimm_security_overwrite_query' was not declared. Should it be static?

This symbol is not used outside of security.c, so this
commit marks it static.
