smbd: remove comments about deprecated 'write cache size'

Browse Source 
The option 'write cache size' was removed since samba-4.12 version:
https://wiki.samba.org/index.php/Samba_4.12_Features_added/changed
https://git.samba.org/?p=samba.git;a=commit;h=3fea05e0
https://git.samba.org/?p=samba.git;a=commit;h=728fabea

It is supposed to remove comments about deprecated 'write cache size',
in order to avoid confusion when reading source code and documents.
