net: nexthop: Have all NH notifiers carry NH ID

Browse source 
When sending the notifications to collect NH statistics for resilient
groups, the driver will need to know the nexthop IDs in individual buckets
to look up the right counter. To that end, move the nexthop ID from struct
nh_notifier_grp_entry_info to nh_notifier_single_info.
