xfsprogs: fix geometry calls on older kernels for 5.2.1

I didn't think 5.2.0 through; the udpate of the geometry ioctl means
that the tools won't work on older kernels that don't support the
v5 ioctls, since I failed to merge Darrick's wrappers.

As a very quick one-off I'd like to merge this to just revert every
geometry call back to the original ioctl, so it keeps working on
older kernels and I'll release 5.2.1.  This hack can go away when
Darrick's wrappers get merged.
