Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver. The problem is the driver assumes the device must have an input report but some malicious devices violate this assumption.

There are three bugs in this code: 1) If we ccp_init_data() fails for &src then we need to free aad. Use goto e_aad instead of goto e_ctx. 2) The label to free the &final_wa was named incorrectly as "e_tag" but it should have been "e_final_wa". One error path leaked &final_wa. 3) The &tag was leaked on one error path. In that case, I added a free before the goto because the resource was local to that block.
