tcptls: Bad file descriptor error when reloading chan_sip

While running through some scenarios using chan_sip and tcp a problem would
occur that resulted in a flood of bad file descriptor messages on the cli:

tcptls.c:712 ast_tcptls_server_root: Accept failed: Bad file descriptor

The message is received because the underlying socket has been closed, so is
valid. This is probably happening because unloading of chan_sip is not atomic.
That however is outside the scope of this patch. This patch simply stops the
logging of multiple occurrences of that message.
