selftests/vm/gup_benchmark.c: match gup struct to kernel
[ Upstream commit 91cd63d320f84dcbf21d4327f31f7e1f85adebd0 ]
An expansion field was added to the kernel copy of this structure for
future use. See mm/gup_benchmark.c.
Add the same expansion field here, so that the IOCTL command decodes
correctly. Otherwise, it fails with EINVAL.
