selftests/cgroup: fix uninitialized variables in test_zswap.c

Browse Source 
First of all, in order to build with clang at all, one must first apply
Valentin Obst's build fix for LLVM [1]. Once that is done, then when
building with clang, via:

    make LLVM=1 -C tools/testing/selftests

...clang finds and warning about some uninitialized variables. Fix these
by initializing them.
