[PATCH] nvdimm: make security_show static

[Ben Dooks <ben.dooks@codethink.co.uk>]

The security_show function is not used outsid 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?
