Subject: cifs: fix leak in FSCTL_ENUM_SNAPS response handling
From: David Disseldorp <ddiss@suse.de>
commit 0e5c795592930d51fd30d53a2e7b73cba022a29b upstream.
The server may respond with success, and an output buffer less than
sizeof(struct smb_snapshot_array) in length. Do not leak the output
buffer in this case.
Fixes: 834170c85978 ("Enable previous version support")
