Retry FreeRTOS_connect() on ETIMEDOUT/ENOTCONN in the multithread TLS client

Browse Source 
The network stack (PHY link, ARP for the gateway) isn't necessarily
ready the instant a connection task starts, so a connect attempt made
too early fails with ETIMEDOUT(-116) or ENOTCONN(-128). The
non-multithreaded caller in test_main.c already retries around its own
wolfSSL_TLS_client_do() call for exactly this; TLS_MULTITHREAD_TEST's
per-task connections had no equivalent, so they'd fail outright instead
of retrying. Close and recreate the socket each attempt, since its
state after a failed connect isn't reusable.
