Wojciech Lukowicz bd4081fa1c io_uring: fix return value when removing provided buffers ... [ Upstream commit c0921e51dab767ef5adf6175c4a0ba3c6e1074a3 ] When a request to remove buffers is submitted, and the given number to be removed is larger than available in the specified buffer group, the resulting CQE result will be the number of removed buffers + 1, which is 1 more than it should be. Previously, the head was part of the list and it got removed after the loop, so the increment was needed. Now, the head is not an element of the list, so the increment shouldn't be there anymore.
