Some drivers (ab)use the ethtool_ops::get_regs operation to expose
only a hardware revision ID. Commit
a77f5db361 ('ethtool: Allocate register
dump buffer with vmalloc()') had the side-effect of breaking these, as
vmalloc() returns a null pointer for size=0 whereas kmalloc() did not.
For backward-compatibility, allow zero-length dumps again.

This patch add the missing dma_unmap().
Which solved the critical issue of system freeze on heavy load.
Michal Miroslaw's rejected patch:
[PATCH v2 10/46] net: jme: convert to generic DMA API
Pointed out the issue also, thank you Michal.
But the fix was incorrect. It would unmap needed address
when low memory.
Got lots of feedback from End user and Gentoo Bugzilla.

Thank you all. :)

There are two problems:
1) "n" was allocated with alloc_skb() so we should free it with
kfree_skb() instead of regular kfree().
2) We return the freed pointer instead of NULL.

Now when all devices are cleaned up, bond can be cleaned up as well
- remove bond->vlgrp
- remove bond_vlan_rx_register
- substitute necessary occurences of vlan_group_get_device
