[PATCH -next] libnvdimm/security: Make __nvdimm_security_overwrite_query() static

[Wei Yongjun]

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?

__nvdimm_security_overwrite_query() is not used outside of this
file, so marks it static.
