dmu_zfetch organize streams with list，not avl_node_t. The reason it works well is zfs's list convert avl_node* to list*,so no warning happened.

The DMU zfetch code organizes streams with lists not avl trees. A avl_node_t was mistakenly used for a list_node_t in the zstream_t type. This is incorrect (but harmless) and when unnoticed because: 1) The list functions explicitly cast the value preventing a warning, 2) sizeof(avl_node_t) >= sizeof(list_node_t) so no overrun occurs, and 3) The calculated offset is the same regardless of the type. Signed-off-by: Brian Behlendorf <[email protected]> Closes openzfs#1946
