Use 2 separate variables of types int and unsigned long long instead of
confusing them. This corrects the correct print format for each of them
and removes the build warning:
warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type
‘long long unsigned int’
Fixes: a4cb3b243343 ("selftests: mm: add a test for remapping to area
immediately after existing mapping")

Changes since v1:
- Don't just fix the print format, instead use different variables
