e8de615950 scst: Move RTPG and STPG handling into the SCST core 
This patch does not change the behavior when using one of the vdisk handlers.
When using dev_disk to forward SCSI commands from one SCST node to another,
this patch causes RTPG and STPG commands to be processed on the source SCST
node (as it should) instead of on the destination SCST node.

overrun-buffer-arg: Overrunning struct type scst_event of 64 bytes by
passing it to a function which accesses it at byte offset 3135 using
argument 64UL + payload_len (which evaluates to 3136). [Note: The source
code implementation of the function has been overridden by a builtin model.]

failure.

6ce21edf8b qla2x00t-32gbit: Fix fabric scan hang 
On timeout, SRB pointer was cleared from outstanding command array and
dropped.  It was not allowed to go through the done process and cleanup.
This patch will abort the SRB where FW will return it with an error status
and resume the normal cleanup.
