[Prevent] Fix prevent issue

- src/co_call.c: buffer_size_warning
Calling strncpy with a maximum size argument of 83 bytes on destination
array "co->cna.name" of size 83 bytes might leave the destination string
unterminated.

- src/co_call.c: dead_error_line
Execution cannot reach this statement "continue;".

- src/co_sat.c: check_after_deref
Null-checking "address" suggests that it may be null, but it has already
been dereferenced on all paths leading to the check.

- src/at.c: suspicious_sizeof
Passing argument "at->resp" of type "TcoreATResponse *" and argument
"4 /* sizeof (TcoreATResponse *) */" to function "tcore_pending_emit_
response_callback(TcorePending *, int, void const *)" is suspicious.
Did you intend to use "sizeof(TcoreATResponse)" instead of "sizeof
(TcoreATResponse *)" ?
