io_uring: zero big_cqe for aux CQEs on CQE32 rings

Browse source

io_fill_cqe_aux() only clears big_cqe if cqe32 is set, which is only the
case for CQE_MIXED. On a CQE32 ring every CQE is 32b, and the extra 16b
are left holding whatever was in that slot before.

Clear it for CQE32 rings as well, like it was before CQE_MIXED support
was added.
