[SCSI] cxgb3i: Fix spelling errors in documentation

============

The Chelsio T3 ASIC based Adapters (S310, S320, S302, S304, Mezz cards, etc.

series of products) supports iSCSI acceleration and iSCSI Direct Data Placement

(DDP) where the hardware handles the expensive byte touching operations, such

as CRC computation and verification, and direct DMA to the final host memory

destination:

	  On receving, S3 h/w recovers the iSCSI PDU by reassembling TCP

3. edit /etc/iscsi/iscsid.conf

   The default setting for MaxRecvDataSegmentLength (131072) is too big,

   replace "node.conn[0].iscsi.MaxRecvDataSegmentLength" to be a value no

   bigger than 15360 (for example 8192):
