Fix: Safely quit remote session by checking remotehost_public attribute

Added a guard to verify `remotehost_public` exists before accessing it to
prevent attribute errors during session cleanup.

Updated across:

tcpdump.py,
perf_test.py,
netperf_test.py,
uperf_test.py,
network_test.py and multiport_stress.py.
