cifs: fix leak in FSCTL_ENUM_SNAPS response handling

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")
