In the case the chip is undergoing different invasive operation which requires a chip reset, all NOPOUT request during this period must be silently dropped from queuing to the hardware. This patch will respond to libiscsi immediately with sent success. Since the request was not actually sent, the NOPIN wait timeout will get triggered and another NOPOUT request will commence through the proper channel.
