[PATCH 2/4] kselftest_module.h: unconditionally expand the KSTM_MODULE_GLOBALS() macro

[Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>]

Two out of three users of the kselftest_module.h header
manually define the failed_tests/total_tests variables instead of
making use of the KSTM_MODULE_GLOBALS() macro. However, instead of
just replacing those definitions with an invocation of that macro,
just unconditionally define them in the header file itself.

A coming change will add a few more global variables, and at least one
of those will be referenced from kstm_report() - however, that's not
possible currently, since when the definition is postponed until the
test module invokes KSTM_MODULE_GLOBALS(), the variable is not defined
by the time the compiler parses kstm_report().
