Summary:                    [patch] Chan_dahdi hangs up after first ring when
doing dtmf cid detection without polarity reversal
Description: 
I believe this issue is related to closed bugs 16460 and 9096.
Seen when doing dtmf callerid detection without polarity reversal:
cidsignalling=dtmf
cidstart=dtmf
CID is properly detected, and the first ring is detected.
The dahdi channel is then hungup, and a second ring is detected (without
CID).
The (external) caller is not disconnected.

Chan_dahdi does not retain CID when detecting DTMF CID without polarity
reversal.

Looks like an unintended change when sig_analog.c was extracted from
chan_dahdi.c.

Removed useless conditional around needed code and fixed resulting
compiler warning.
