config/kmap_atomic: initialise test data

Browse Source 
6.18 changes kmap_atomic() to take a const pointer. This is no problem
for the places we use it, but Clang fails the test due to a warning
about being unable to guarantee that uninitialised data will definitely
not change. Easily solved by forcibly initialising it.
