input: remove OpenInputDevice and CloseInputDevice DDX hooks.

In theory, these hooks were to be used for DDX-specific device enablement.
None of the DDXs however did anything here. Now we call DEVICE_INIT on all
devices when they are added, so the xfree86 DDX as the only one with real
code didn't do anything here.

kdrive checked for device validity but that's already handled in
ProcXOpenDevice.
