[PATCH 2/4] isdn: accept CAPI Informational Info values as success

[Tilman Schmidt]

Info values in the 0x00xx range are defined in the CAPI standard
as "Informational, message processed successfully". Therefore a
CONNECT_B3_CONF message with an Info value in that range should
open an NCCI just as with Info==0.

Impact: minor bugfix
