net-sysfs: get_netdev_queue_index() cleanup 

Redo commit ed1acc8cd8.

Commit 822b3b2ebf ("net: Add max rate tx queue
attribute") moved get_netdev_queue_index around, but kept the old version.
Probably because of a reuse of the original patch from before Eric's change to
that function.

Remove one inline keyword, and no need for a loop to find
an index into a table.
