Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy().

Previous error handling path was unique for all
possible errors and there was unnecessary branching.
Also, one step for freeing drv_sw was missing. All
these problems was fixed by restructuring error
handling path.
Also, moved out free_netdev() from r8712_free_drv_sw() for
correct error handling.
