cifs: fix potential use-after-free bugs

Ensure that share and prefix variables are set to NULL after kfree()
when looping through DFS targets in __tree_connect_dfs_target().

Also, get rid of @ref in __tree_connect_dfs_target() and just pass a
boolean to indicate whether we're handling link targets or not.

Fixes: 631f7087f623 ("cifs: support nested dfs links over reconnect")
