Coccinelle: Add iterators/list_entry_update.cocci

list_for_each_entry uses its first argument to get from one element of
the list to the next, so it is usually not a good idea to reassign it.
The first rule finds such a reassignment and the second rule checks
that there is a path from the reassignment back to the top of the loop.
