[ Upstream commit 44b02da39210e6dd67e39ff1f48d30c56d384240 ]
Commit 12927835d211 ("greybus: loopback: Add asynchronous bi-directional support") does what it says on the tin - namely, adds support for asynchronous bi-directional loopback operations.
What it neglects to do though is increment the per-connection gb->iteration_count on an asynchronous operation error. This patch fixes that omission.
