[PATCH] unicode: make utf8 test count static

[Ben Dooks]

The variables failed_tests and total_tests are not used outside of the
utf8-selftest.c file so make them static to avoid the following warnings:

fs/unicode/utf8-selftest.c:17:14: warning: symbol 'failed_tests' was not declared. Should it be static?
fs/unicode/utf8-selftest.c:18:14: warning: symbol 'total_tests' was not declared. Should it be static?
