[ Upstream commit 64cc377b7628b81ffdbdb1c6bacfba895dcac3f8 ]
The code to check for replay is not just -EAGAIN. In some cases, the send request or receive response may result in network errors, which we're now mapping to -ECONNABORTED.
This change introduces a helper function which checks if the error returned in one of the above two errors. And all checks for replays will now use this helper.
