[VOTE] BP-61: Revert BP-59 to release ByteBuf using ReferenceCountUtil.release() instead of ReferenceCountUtil.safeRelease()

[Hang Chen]

Hi, All

After a fascinating discussion, I would start the vote for BP-61.

We will replace the `ReferenceCountUtil.safeRelease()` with
`ReferenceCountUtil.release()`.

Please leave +1/-1 in this thread to join the vote. And feel free to
leave any concerns.

Thanks to you guys.

Best,
Hang
