[PATCH xf86-input-libinput] Unref the libinput context on pre_init failure

[Peter Hutterer]

A device that fails pre_init has a ref to the libinput context but may not
have a pInfo->private. For those devices we never call libinput_unref() and
the libinput struct never gets freed.

Thus if at least one device didn't pass pre_init, we never cleaned up after
ourselves.
