Shuhei Matsumoto 84f59335c2 lib/iscsi: Send R2T in SCSI Data-Out PDU Header handling 
Recent patches refactored iSCSI target to separate PDU header
and payload handling. However for SCSI Data-Out PDU, the division
of roles done by refactoring was wrong. Before refactoring, LUN
hotplug was checked after sending R2T, but after refactoring LUN
hotplug is checked before sending R2T. This change stopped PDU
exchange between iSCSI initiator and target and caused timeout of
LUN removal.

This patch restores the original ordering of checking LUN hotplug
and sending R2T by changing the division of roles.

SCSI Write Command PDU handling don't have any issue related with
this.

Fixes #1004
