From: Johan Hovold <johan@kernel.org>
[ Upstream commit 56445eef55cb5904096fed7a73cf87b755dfffc7 ]
Fix interrupt-out transfer length which was being set to the transfer-buffer length rather than the size of the outgoing packet.
Note that no slab data was leaked as the whole transfer buffer is always cleared before each transfer.
