Daniel Borkmann 7b0c2a0508 bpf: inline map in map lookup functions for array and htab ...

Avoid two successive functions calls for the map in map lookup, first
is the bpf_map_lookup_elem() helper call, and second the callback via
map->ops->map_lookup_elem() to get to the map in map implementation.
Implementation inlines array and htab flavor for map in map lookups.
