[PATCH] selftests/mm: Deduplicate test names in madv_populate

[Mark Brown <broonie@kernel.org>]

The madv_populate selftest has some repetitive code for several different
cases that it covers, included repeated test names used in ksft_test_result()
reports. This causes problems for automation, the test name is used to both
track the test between runs and distinguish between multiple tests within
the same run. Fix this by tweaking the messages with duplication to be more
specific about the contexts they're in.
