I've looked a little more into to this, and I'm not so sure we can get
rid of the gd->flags |= GD_FLG_RECORD; in console_record_reset_enable().

Removing the flag seems to break quite some tests in
test/py/tests/test_ut.py.

The breakage can be explained that various unit tests clear the
GD_FLG_RECORD with:

	gd->flags &= ~GD_FLG_RECORD;

Therefore, I would suggest we keep the flag in
console_record_reset_enable().
