[PATCH 3/3] libnvdimm: mark 'security_show' static again

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The security_show() function was made global and __weak at some
point to allow overriding it. The override was removed later, but
it remains global, which causes a warning about the missing
declaration:

drivers/nvdimm/dimm_devs.c:352:9: error: no previous prototype for 'security_show'

This is also not an appropriate name for a global symbol in the
kernel, so just make it static again.

Fixes: 15a8348707ff ("libnvdimm: Introduce CONFIG_NVDIMM_SECURITY_TEST flag")
