wayland/drm-lease: Hold device fd when listing leases

Browse source 
In multi-GPU setups, when one of the GPUs is used to render the desktop
and the other one has all of their devices available for lease,
meta_kms_impl_device_list_lessees() can be called after the device fd
has been unhold.

Make sure to hold and unhold it in this function.
