Clear IB_CFG_DONE on receiving peer config request when channel open 

Root Cause: Configure request fails in CST_OPEN state
after a configure request IB_CFG_DONE and OB_CFG_DONE both are
cleared. Some IOT devices try to configure again in the CST_OPEN
state which fails if OB_CFG_DONE is cleared.

Fix: Clear IB_CFG_DONE and keep OB_CFG_DONE unchanged on receiving
Peer config request when channel open.

Test: Tested with Geely Carkit.
