smb: server: let send_done handle a completion without IB_SEND_SIGNALED

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

smb: server: let send_done handle a completion without IB_SEND_SIGNALED

With smbdirect_send_batch processing we likely have requests without
IB_SEND_SIGNALED, which will be destroyed in the final request
that has IB_SEND_SIGNALED set.

If the connection is broken all requests are signaled
even without explicit IB_SEND_SIGNALED.
