Subject: [PATCH] [SCSI] iscsi class: fix gfp use in ping compl and host event

If a ping or host event were to occur when memory is low
we do not want to use GFP_KERNEL, because the paths
sending them cannot block for data to be written. These
paths might be needed to recover write paths. Use GFP_NOIO
instead.
