vfs_default_durable_reconnect_check_stat()
This makes vfs_default_durable_reconnect() simpler to read
and it reduces code duplication in the failure case handling.

reconnect.
At durable reconnect, we check the stat info stored in the cookie against the
current stat data from the file we just opened. If any detail differs, we deny
the durable reconnect, because in that case it is very likely that someone
opened the file while the handle was disconnected, which has to be interpreted
as an oplock break.

If we close the low level FD, we should better update the write_time
if needed.
It's not unlikely that the client doesn't reclaim the durable handle,
in that case we may not close the after the durable timeout.
In such a case we should make sure that we at least update the write time
on disconnect, this makes sure backup applications notice that
the file was changed.

We need to call the pending write time update handler immediately.
Which means we don't wait exactly 2 seconds before updating the write time
after the first write.

Found by Ambi's state-of-the-art compiler!

We only grant durable handles for CIFS/SMB2 only access,
that means "kernel oplocks", "kernel share modes" and "posix locking"
need to be set to "no".
For now we also don't grant durable handles if delete on close
is active on the handle.
