ipv4: nexthop: Reduce allocation size of 'struct nh_group'
The struct looks as follows:
struct nh_group {
struct nh_group *spare; /* spare group for removals */
u16 num_nh;
bool mpath;
bool fdb_nh;
bool has_v4;
struct nh_grp_entry nh_entries[];
};
But its offset within 'struct nexthop' is also taken into account to
determine the allocation size.
Instead, use struct_size() to allocate only the required number of
bytes.
