Matthew Jordan (361705):

>Prevent invalid access of free'd memory if DAHDI channel during an MWI event
>
>In the MWI processing loop, when a valid event occurs the temporary caller ID
>information is deallocated.  If a new DAHDI channel is successfully created, 
>the event is passed up to the analog_ss_thread without error and the loop
>exits.  If, however, the DAHDI channel is not created, then the caller ID
>struct has been free'd, and the gains reset to their previous level.  This
>will almost certainly cause an invalid access to the free'd memory, either
>in subsequent calls to callerid_free or calls to callerid_feed.
>
>This patch makes it so that we only free the caller ID structure if a
>DAHDI channel is successfully created, and we bump the gains back up
>if we fail to make a DAHDI channel.
