When ice driver reads recipes from firmware information about need_pass_l2 and allow_pass_l2 flags is not stored correctly. Those flags are stored as one bit each in ice_sw_recipe structure. Because of that, the result of checking a flag has to be casted to bool. Note that the need_pass_l2 flag currently works correctly, because it's stored in the first bit.
