iser-target: Disable TX completion interrupt coalescing
This patch explicitly disables TX completion interrupt coalescing logic
in isert_put_response() and isert_put_datain() that was originally added
as an efficiency optimization in commit 95b60f07.
It has been reported that this change can trigger ABORT_TASK timeouts
under certain small block workloads, where disabling coalescing was
required for stability. According to Sagi, this doesn't impact
overall performance, so go ahead and disable it for now.
