Fix: Make the case []interface{} processed consist with the case primitve.A

[LinPr]

make the case []interface{} processed consist with the case primitve.A, just like the upper case bson.M and case map[string]interface{} have the same handle function.

I think we can simplify this and merge this case with primitive.A

case primitive.A, []interface{}: res = append(res, processSlice(nextPrefix, v, l, compatibleMode)...)
