[SCSI] libiscsi: Check TMF state before sending PDU
Patch and mail from both MikeC and HannesR:
Before we're trying to send a PDU we have to check whether a TMF
is active. If so and if the PDU will be affected by the TMF
we should allow only Data-out PDUs to be sent.
If fast_abort is set, no Data-out PDUs will be sent while
a LUN reset is being processed for a affected LUN.
fast_abort is now ingored during a ABORT TASK tmf. We will not
send any Data-outs for a task if the task is being aborted.
