Subject: dahdi_cfg: DAHDI_INDIRECT -> DAHDI_SPECIFY when configuring pciradio
 channels.

While slightly less efficient, this is only used when configuring the
channels initially (not the hot path) and allows dahdi-base.c to assume
that the open "file" pointer always refers to the channel on which to
perform the operation.
