Ronnie Sahlberg c29b9a2aae Add a new "iscsi_queue_length()" which will tell us how many commands ...

are in flight at the moment.
Aside from commands, we also consider the "has not yet connected completely" as being an i/o.

When this command returns 0 it means we are connected ant the iscsi connection is idle, with no commands in flight.

KVM needs a function to detect idleness like this for its block layer io_flush
function.
