setting rp_filter=2 from second session on will not work in some cases.

I coded it (loosening only on the second interface) but had problems in my 
tests. If the first connection to iscsi happens through a device not expected 
by the OS as the device for that connection, the rp_filter=2 is needed for the 
first connection. I will improve this code, but I have to keep the rp_filter=2 
for the first connection as well.
