[RFC PATCH 04/16] selftests/membarrier: Issue the sync core command in its test

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

test_membarrier_private_expedited_sync_core_success() is meant to
check that MEMBARRIER_CMD_PRIVATE_EXPEDITED_SYNC_CORE succeeds after
its registration. It issues MEMBARRIER_CMD_PRIVATE_EXPEDITED instead.
No test issues the sync core command with success.

Issue the sync core command.

While at it, pass the third system call argument. It was left
uninitialized.

Fixes: 460e8c3340a2 ("membarrier/selftest: Test private expedited sync core command")
