cifs: Fix memory and information leak in smb3_reconfigure()

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

cifs: Fix memory and information leak in smb3_reconfigure()

In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the
function returns immediately without freeing and erasing the newly
allocated new_password and new_password2. This causes both a memory leak
and a potential information leak.

Fix this by calling kfree_sensitive() on both password buffers before
returning in this error case.
