xfrm: Add explicit dev to .xdo_dev_state_{add,delete,free}
Previously, device driver IPSec offload implementations would fall into
two categories:
1. Those that used xso.dev to determine the offload device.
2. Those that used xso.real_dev to determine the offload device.
The first category didn't work with bonding while the second did.
In a non-bonding setup the two pointers are the same.
This commit adds explicit pointers for the offload netdevice to
.xdo_dev_state_add() / .xdo_dev_state_delete() / .xdo_dev_state_free()
which eliminates the confusion and allows drivers from the first
category to work with bonding.
xso.real_dev now becomes a private pointer managed by the bonding
driver.
