Subject: [PATCH v4] um: vector: Fix exception handling in vector_eth_configure()

The resource cleanup was incomplete in the implementation 
of the function "vector_eth_configure".
Thus replace the jump target
"out_undo_user_init" by "out_free_netdev".
Delate the orphan function "out_undo_user_init"

PATCH v1-v3: Modify the patch format.
