nvdimm: make security_show static

The security_show function is not used outside of drivers/nvdimm/dimm_devs.c
and the attribute it is for is also already static. Silence the sparse
warning for this not being declared by making it static. Fixes:

  drivers/nvdimm/dimm_devs.c:352:9: warning: symbol 'security_show' was not declared. Should it be static?
