GangCao 6b7e9d0af2 Lib/iSCSI: add the LUN Resize support 
From SAM-4, section 5.13 (Sense Data);
“When a command terminates with a CHECK CONDITION status, sense data shall be returned
in the same I_T_L_Q nexus transaction (see 3.1.50) as the CHECK CONDITION status. After
the sense data is returned, it shall be cleared except when it is associated with a unit
attention condition and the UA_INTLCK_CTRL field in the Control mode page (see SPC-4)
contains 10b or 11b.”

SPDK does not set UA_INTLCK_CTRL to 10b or 11b, so we set the unit attention condition
immediately against a single IO or Admin IO after reporting it via a CHECK CONDITION.
Once the failed IO received at iSCSI initiator side, it will be retried. In the case of
resize operation, if there is no IO from iSCSI initiator side, the unit attention
condition will be delayed to report until the first IO is received at the iSCSI target
side.

Meanwhile, we clear the resizing (newly added) flag on our SCSI LUN structure after
first time we report the resize unit attention condition.

The kernel initiator won’t actually resize the corresponding block device automatically.
It will report a uevent, and then you can set up udev rules to trigger a rescan. SPDK
iSCSI initiator will automatically report the LUN size change.
