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.

I'd like to just have libiscsi handle a error code here instead of hacking around its lack of eh handling.
