I should say the netdev_name_in_use() in dev_prep_valid_name() return -EEXIST.

This is not a fix. 

There are three callers to dev_prep_valid_name(), only dev_alloc_name() needs
to replace -EEXIST with -ENFILE. We shouldn't add an extra parameter for this,
because it's not necessary for the other callers.

If we do it in dev_alloc_name(), the other callers can save a parameter.
