Previously the identifier used for indirect block callback registry and
for block rule cb registry (when done via indirect blocks) was the pointer
to the netdev we were interested in receiving updates on. This worked fine
if a single app existed that registered one callback per netdev of
interest. However, if multiple cards are in place and, in turn, multiple
apps, then each app may register the same callback with the same
identifier to both the netdev's indirect block cb list and to a block's cb
list. This can lead to EEXIST errors and/or incorrect cb deletions.
Prevent this conflict by using the app pointer as the identifier for
netdev indirect block cb registry, allowing each app to register a unique
callback per netdev. For block cb registry, the same app may register
multiple cbs to the same block if using TC shared blocks. Instead of the
app, use the pointer to the allocated cb_priv data as the identifier here.
This means that there can be a unique block callback for each app/netdev
combo.
