Trusty: Move tipc fuzzer connection to end of iteration
We detect a TA crash by not being able to reconnect to its channel. We
were previously connecting to the TA at the beginning of each fuzz
iteration, but this results in only detecting a crash on the following
iteration. By moving this connection to the end of the fuzz iteration,
we can detect a crash corresponding to the correct fuzz iteration and
libFuzzer will produce the correct crashing input.
