caif: __dev_get_by_index instead of dev_get_by_index to find interface
The following call chains indicate that chnl_net_open() is under
rtnl_lock protection as __dev_open() is protected by rtnl_lock.
So if __dev_get_by_index() instead of dev_get_by_index() is used
to find interface handler in it, this would help us avoid to change
interface reference counter.
__dev_open()
chnl_net_open()
