Subject: [PATCH v2] selftests: arm64: Fix -Waddress warning in tpidr2 test

Resolve compiler warning about always true condition in ksft_test_result
in tpidr2, passing actual function.

This silences -Waddress warning while maintaining test functionality.

Fixes compiler warning (similar for other functions):
warning: the address of 'write_read' will always evaluate as
'true' [-Waddress]

Fixes: 6d80cb73131d ("kselftest/arm64: Convert tpidr2 test to use kselftest.h")
