scsi: qla1280: Fix kernel oops when debug level > 2

Browse Source 
[ Upstream commit 5233e3235dec3065ccc632729675575dbe3c6b8a ]

A null dereference or oops exception will eventually occur when qla1280.c
driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2.  I
think its clear from the code that the intention here is sg_dma_len(s) not
length of sg_next(s) when printing the debug info.
