Don't compile in unused reparse point symlink code
Recent Windows versions now create symlinks more frequently
and they do use this "reparse point" symlink mechanism. We can of course
do symlinks nicely to Samba and other servers which support the
CIFS Unix Extensions and we can also do SFU symlinks and "client only"
"MF" symlinks optionally, but for recent Windows we currently can not
handle the common "reparse point" symlinks fully, removing the caller
for this. We will need to extend and reenable this "reparse point" worker
code in cifs and fix cifs_symlink to call this. In the interim this code
has been moved to its own config option so it is not compiled in by default
until cifs_symlink fixed up (and tested) to use this.
