usb: typec: ucsi: displayport: Fix NULL pointer dereference
If the registration of the DisplayPort was not successful,
or if the port does not support DisplayPort alt mode in the
first place, the function ucsi_displayport_remove_partner()
will fail with NULL pointer dereference when it attempts to
access the driver data.
Adding a check to the function to make sure there really is
driver data for the device before modifying it.
