[PATCH libteam] teamd: lacp: use teamd_log_dbgx to print lacp info state

[Hangbin Liu]

When we set TEAM_LOG_OUTPUT=syslog in the environment, all the logs,
including debug info will be printed to syslog, even though we set
daemon_verbosity_level = LOG_INFO.

The reason is the function daemon_logv() of libdaemon only check the
daemon_verbosity_level for LOG_STDOUT and LOG_STDERR, not LOG_SYSLOG.
Also here is the quote for daemon_set_verbosity() from libdaemon/dlog.h
"""
Allows to decide which messages to output on standard output/error
streams. All messages are logged to syslog and this setting does
not influence that.
"""

So libdaemon is intend to print all logs to syslog. But when we also
enabled lacp fast_rate, the lacp state info may get a little annoying
as it will print the state info every second, even the log level is
LOG_INFO.

So let's use teamd_log_dbgx() to print lacp info state, which would
only print the state log message with -g option.
