smb: client: guarantee refcounted children from parent session

In the Linux kernel, the following vulnerability has been resolved:

smb: client: guarantee refcounted children from parent session

Avoid potential use-after-free bugs when walking DFS referrals,
mounting and performing DFS failover by ensuring that all children
from parent @tcon->ses are also refcounted.  They're all needed across
the entire DFS mount.  Get rid of @tcon->dfs_ses_list while we're at
it, too.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
