[tcp] fix minor bugs (#7335)

Browse Source 
This commit fixes minor bugs in TCP.

1. The first change fixes a bug where the TCP CLI prints out an
incorrect message when a connection is terminated. This appears to
have been introduced in #7279.

2. The second change fixes a null pointer dereference when accepting a
TCP connection. This issue is purely theoretical at the moment,
because in the case where the dereferenced pointer is NULL, the
dereferenced value is not used, and so the compiler optimizes out the
memory access (so it seems). As a result, TCP actually runs without
issues. But I've fixed it anyway, to avoid depending on that behavior.
