wifi: rtw89: 8922a: set random mac if efuse contains zeroes

Browse source

[ Upstream commit 41be33d3ef ]

I have some rtl8922ae devices with no permanent mac stored in efuse.

It could be properly saved and/or configured from user tools like
NetworkManager, but it would be desirable to be able to initialize it
somehow to get the device working by default.

So, in the same way as with other devices, if the mac address read from
efuse contains zeros, a random mac address is assigned to at least allow
operation, and the user is warned about this in case any action needs to
be considered.
