dev: support deferring device flag change notifications
Split dev_change_flags() into two functions: __dev_change_flags() to
perform the actual changes and __dev_notify_flags() to invoke netdevice
notifiers. This will be used by rtnl_link to defer netlink notifications
until the device has been fully configured.
This changes ordering of some operations, in particular:
- netlink notifications are sent after all changes have been performed.
As a side effect this surpresses one unnecessary netlink message when
the IFF_UP and other flags are changed simultaneously.
- The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked
after all changes have been performed. Their relative is unchanged.
- net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead
of afterwards. This should not make any difference since both RX and TX
are already shut down at this point.
