[dts] [PATCH V1] fix FreeBSD get mac addr error

[Liu, Yong]

Unload driver is very critical action, some cases will use this function to get mac address.
Thus will lead to all suites after these cases.

Please do this kind of action in upper layer which handler the overall execution.

Thanks,
Marvin
