Since commit 509db2833e0d ("bpf: error handling when map_lookup_elem
isn't supported") when map lookup isn't supported, the map_lookup_elem
function should return ERR_PTR(-EOPNOTSUPP).
Fixes: f1a2e44a3aec ("bpf: add queue and stack maps")
Signed-off-by: Prashant Bh
This set fixes map_lookup_elem return value for queue/stack map.
Also adds verifier tests to check whether verifier prevents lookup on
these maps.
Note that patch 2 isn't dependant on patch 1. The verifier prevents
lookup on queue/stack map because key size is zero.
