[PATCH] tools/testing/nvdimm: Fix security_init() symbol collision

[Dan Williams]

Starting with the new perf-event support in the nvdimm core, the
nfit_test mock module stops compiling. Rename its security_init() to
nfit_security_init().

tools/testing/nvdimm/test/nfit.c:1845:13: error: conflicting types for 
‘security_init’; have ‘void(struct nfit_test *)’
 1845 | static void security_init(struct nfit_test *t)
