[PATCH] mISDNuser: mISDNcapid: fix lPLCIDisconnectInd() by returning zero when B3 link is missing

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

The function lPLCIDisconnectInd() is called by plci_cc_disconnect_ind() when a
EV_L3_DISCONNECT_IND event is being handled. If the B3 link has already gone,
lPLCIDisconnectInd() returns -ENODEV, which prevents plci_cc_disconnect_ind()
from calling lPLCILinkDown() and therefore from cleaning up properly. This
commit makes lPLCIDisconnectInd() returns zero (i.e. success) in such a
situation.
