Connection last_ping is not being updated when iscsi_send_nopout fails.
Not updating the last_ping will cause firing a timer to a past time
(last_ping + ping_tmo < current_time) which triggers an infinite loop of
iscsi_check_transport_timeouts() and hogs the cpu.
Fix this issue by checking the return value of iscsi_send_nopout.
If it fails set the next_timeout to one second later.
