CVE-2024-46796

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix double put of @cfile in smb2_set_path_size()

If smb2_compound_op() is called with a valid @cfile and returned
-EINVAL, we need to call cifs_get_writable_path() before retrying it
as the reference of @cfile was already dropped by previous call.

This fixes the following KASAN splat when running fstests generic/013
against Windows Server 2022:
