[SCSI] iscsi lib: have lib create work queue for transmitting IO
We were using the shost work queue which ended up being a little akward since all iscsi hosts need a thread for scanning, but only drivers hooked into libiscsi need a workqueue for transmitting. So this patch moves the xmit workqueue to the lib. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
