Summary:                    CallCompletionRequest() / Cancel() exit non-zero if
no call/pending call
Description: 
When Calling CallCompletionRequest() if there is no call to make a request
on (timer has expired), or there is already a pending request (in generic
mode) then the call returns with a non-zero return and hangs up the call.

When this happens, in both above scenarios, the following is printed out
the the log/clli:

[Feb  7 09:22:28] CC[10693]: ccss.c:3886 ccreq_exec: Couldn't find a core
instance for caller SIP/3000

in the case where there is a pending request, it is the same message, but
as a result that there was a pending request and thus no instance was saved
from the last call since all 'slots' were taken (max 1 slot for generic).

example, the following occurs upon making a subsequent call elsewhere if
you have a current pending request, thus the above equivalent behavior in
both cases:

[Feb  7 09:22:08] CC[10670]: ccss.c:1522 cc_monitor_destroy: Core 77:
Calling destructor for monitor 2000 at from-internal
[Feb  7 09:22:08] CC[10670]: ccss.c:1415 cc_interface_destroy: Destroying
cc interface 2000 at from-internal
[Feb  7 09:22:08] CC[9099]: ccss.c:2944 cc_do_state_change: Core 77: State
change to 1 requested. Reason: CC offered to caller SIP/3000-00000106
[Feb  7 09:22:08] CC[9099]: ccss.c:2947 cc_do_state_change: Core 77:
Unable to find core instance.

Similar issue when calling CallCompletionCancel() if there is no pending
request to cancel. This results in a non-zero exit as well, but no log
message from the ccss system:


    -- Executing [*83 at from-internal:5]
CallCompletionCancel("SIP/3000-0000010a", "") in new stack
  == Spawn extension (from-internal, *83, 5) exited non-zero on
'SIP/3000-0000010a'
