We recently shuffled this code around and introduced a new error path
before *resp_buf_type gets initialized. It creates uninitialized
variable bugs in the callers.
fs/cifs/smb2pdu.c:579 SMB2_negotiate()
error: uninitialized symbol 'resp_buftype'.
Fixes: 738f9de5cdb9 ("CIFS: Send RFC1001 length in a separate iov")
