[SCSI] libiscsi: fix nop handling
During root boot and shutdown the target could send us nops.
At this time iscsid cannot be running, so the target will drop
the session and the boot or shutdown will hang.
To handle this and allow us to better control when to check the network
this patch moves the nop handling to the kernel.
