Subject: [PATCH] Bluetooth: Clear role switch pending flag

If role switch was rejected by the controller and HCI Event: Command Status
returned with status "Command Disallowed" (0x0C) the flag
HCI_CONN_RSWITCH_PEND remains set. No further role switches are
possible as this flag prevents us from sending any new HCI Switch Role
requests and the only way to clear it is to receive a valid
HCI Event Switch Role.

This patch clears the flag if command was rejected.
