[PATCH 6/6] kselftest/arm64: Fix check_user_mem test

From: Vincenzo Frascino
Date: Mon Oct 26 2020 - 08:13:33 EST


The check_user_mem 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.
