BUG/MINOR: master/cli: properly trim the '@@' process name in error messages

Browse Source 
When '@@' alone is sent on the master CLI (no trailing LF), we get an
error that displays anything past these two characters in the buffer
since there's no room for a \0. Let's make sure to limit the length of
the process name in this case. No backport is needed since this was added
with 00c967fac4 ("MINOR: master/cli: support bidirectional communications
with workers").
