Add invalid user_data checker in signal handler

If the time of destroying the wifi handle overlaps
with the time of signal arrival,
there is a possibility that user_data of the wifi handle
that has already been destroyed may be passed in
the signal handler due to timing.
Because this may cause malfunctions,
code to verify user_data has been added.
