wcb4xxp: HDLC packets do not pass over D-channel.
dahdi/wcb4xxp driver used with Digium Wildcard B410 quad-BRI PCI card
unable to communicate with another ISDN device (ISDN phone, another port
of B410). It appears that B-channels are capable to transport data, but
D-channel is not.
Debug output added into the driver shows that packets are transmitted to
the D-channel, but no packets are received. Further investigation shows
that no interrupts received from Rx FIFO associated with D-channel,
although packets are delivered to the FIFO. I've found that problem is
in improper usage of chan->chanpos while indexing the fifo index
(bspan->fifos): chanpos starts from 1 and fifos starts from 0.
Therefore, garbage read instead of fifo number.
(closes issue #14834)
