This moves msft_do_close() from hci_dev_do_close() to
hci_unregister_dev() to avoid clearing MSFT extension info. This also
avoids retrieving MSFT info upon every msft_do_open() if MSFT extension
has been initialized.
The following test steps were performed.

It should be the driver's business to logically separate its VLAN

need / can't do this.
So remove the transactional shim from DSA and let drivers to propagate

As of commit 457e20d65924 ("mlxsw: spectrum_switchdev: Avoid returning

Nope. With netdev, if it is not merged in about 3 days, it needs to be
