mISDN: Support DR6 indication in mISDNipac driver

commit 1e1589ad8b5cb5b8a6781ba5850cf710ada0e919 upstream.

According to figure 39 in PEB3086 data sheet, version 1.4 this indication
replaces DR when layer 1 transition source state is F6.

This fixes mISDN layer 1 getting stuck in F6 state in TE mode on
Dialogic Diva 2.02 card (and possibly others) when NT deactivates it.
