gdb_server: check target before executing event callback 

As debugging multi-targets, every target has its own gdb connection.
If there are two connections, gdb_target_callback_event_handler will
be registered twice.  Everytime event occurs, the registered callback
will be executed twice.  If both targets are running, as user issues
ctrl-c in one gdb client, both connections will send "stop reply" to
GDB clients even TARGET_EVENT_GDB_HALT is caused by one of them.

The commit fix above problem as debugging multi-targets.
