pim6d: Fix crash in ipv6 pim command
Problem:
Execute the below commands, pim6d core happens.
interface ens193
ip address 69.0.0.2/24
ipv6 address 8000::1/120
ipv6 mld
ipv6 pim
We see crash only if the interface is not configured, and
we are executing PIM/MLD commands.
RootCause:
Interface ens193 is not configured. So, it will have
ifindex = 0 and mroute_vif_index = -1.
Currently, we don't enable MLD on an interface if
mroute_vif_index < 0. So, pim_ifp->MLD = NULL.
In the API pim_if_membership_refresh(), we are accessing
pim_ifp->MLD NULL pointer which leads to crash.
Fix:
Added NULL check before accessing pim_ifp->MLD pointer in
the API pim_if_membership_refresh().
