Subject: [PATCH] selftests/mm: Deduplicate second mmap() of 5*PAGE_SIZE at
 base

The map_fixed_noreplace test does two blocks of test starting from a
mapping of 5 pages at the base address, logging a test result for each
initial mapping. These are logged with the same test name, causing test
automation software to see two reports for the same test in a single run.
Tweak the log message for the second one to deduplicate.
