Subject: [PATCH 4/6] kselftest/arm64: Fix check_mmap_options test

The check_mmap_options test reports the error below because the test
plan is not declared correctly:

  # Planned tests != run tests (0 != 22)

Fix the test adding the correct test plan declaration.

Fixes: 53ec81d23213 ("kselftest/arm64: Verify all different mmap MTE options")
