fix null dereference on aeli

EffectProxyCreate does not return fail and assign the pointers in
the aeli when the two effects don't have the flag
EFFECT_FLAG_HW_ACC_TUNNEL. It causes problem when Effect_command
does dereference on those two pointers.

Bug: 182867964
Test: mm libeffectproxy
Test: create effects without EFFECT_FLAG_HW_ACC_TUNNEL
