[PATCH 5/6] kselftest/arm64: Fix check_ksm_options test

[Vincenzo Frascino <vincenzo.frascino@xxxxxxx>]

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

  # Planned tests != run tests (0 != 4)

Fix the test adding the correct test plan declaration.
