Subject: [PATCH -next v2] tools/testing/nvdimm: Make symbol '__nfit_test_ioremap' static

The sparse tool complains as follows:

tools/testing/nvdimm/test/iomap.c:65:14: warning:
 symbol '__nfit_test_ioremap' was not declared. Should it be static?

This symbol is not used outside of iomap.c, so this
commit marks it static.
