Summary:                    Received invalid event that had no device IE
Description: 
 I use Asterisk whith TE410P and 3 weeks ago a upgrade my driver to DAHDI
2.1.0.4, but now I receive error in my E1 dials:

ERROR[26709]: pbx.c:8330 device_state_cb: Received invalid event that had
no device IE
ERROR[26709]: app_queue.c:856 device_state_cb: Received invalid event that
had no device IE

This errors ocurrer after 20 or more simultaneos calls, i use 4 PTSN
connected in this card and the errors ocurer in all. In the other point of
E1 (PSTN) the information is error in E1 frame.

I test to downgrade de version of dahdi or upgrade dahdi to RCx versions
but the error persist in all version tested.

---------------------------------------------------------------------- 
For 1.6.1.0, at least, this will happen if the first side of an AMI
Originate, or, presumably the channel side of a call file call, fails.

ast_pbx_outgoing_exten calls ast_pbx_outgoing_cdr_failed to create a call
detail record, after destroying the original channel.  This creates a
temporary channel structure in order to issue the CDR, but never gives it a
name.  It then calls ast_channel_free, which tries to report a device state
change to INVALID, which has no associated device name.  The error isn't
detected until two process switches later.

Either ast_pbx_outgoing_cdr_failed should provide a dummy name, or
ast_channel_free should recognize a special case and not try to report a
device state change.

I discovered this whilst debugging https://issues.asterisk.org/view.php?id=15314
against Asterisk 1.6.1.0,
although it was unrelated to the real problem there.
