c32f79f6c1 Revert T10-PI support 
The T10-PI patch (r6162) increases the time needed to run mkfs.ext4
over iSCSI from less than a second to several minutes. This is a
regression so revert the T10-PI patch until there is sufficient time
to find the root cause of this regression and to fix this regression.

732ce5ca89 fcst: Handle frame send failures properly 
Retry sending XFER_RDY, data and response frames if the network
driver reports that sending failed (-ENOMEM) instead of reporting
a kernel warning (WARN_ON(1)). If sending XFER_RDY or data frames
failed for another reason, report this to the initiator as a
write error (ASC = 03; ASCQ = 00 which stands for PERIPHERAL
DEVICE WRITE FAULT). If sending a response frame failed with
another error code than -ENOMEM, do not send a response.

d937c0886d fcst: Move exch_done() calls into ft_cmd_done() 
This patch ensures that exch_done() gets called if an fcst
callback returns SCST_TGT_RES_FATAL_ERROR.

420f85c39b fcst: Handle exchange timeout gracefully 
This is a backport of commit e1c4038282c7586c3544542b37872c434669d3ac by
Mark Rustad <mark.d.rustad@intel.com>. This patch avoids that unregistering
a session hangs after an exchange timeout occurred.

50120c37b3 scst_cmd_aborted() is a bad and ambiguous name. Rename it to scst_cmd_aborted_on_xmit() and create a new version, which truly reflects its semantic.

649fef691e Changes to make fcst work on Linux 2.6.36. 
The biggest difference is that libfc no longer allocates a sequence
and exchange for incoming requests, and that eliminates a parameter
on the receive function.  This was done to help performance and
might help on short reads sometime in the future.

This also fixes an error in ft_send_read_data() that exceeds the
skb's SG list length limit on long reads when the NIC
supports large send offload.

I also made other minor changes like adding debugging.
