The local_datapaths are populated by iterating through
all available port bindings or new ones added during I-C.
The port bindings are not ordered, it might happen that
the order between engine runs are different. This can cause
the prefix delegation shash to be with NULL local_datapath.
Even in cases that the port binding is actually part of
the local_datapath. Store only port binding in the shash
and during pinctrl_run check if the stored port binding
is part of local_datapaths. Because pinctrl runs only
after the engine computation is complete we should have
complete hmap of all local_datapaths.
Fixes: 647920b6 ("controller: incrementally create ipv6 prefix delegation
port_binding list")
