[Bug 1702529] [NEW] ACCESS_DENIED with symlinks within a root ("/") share

[Impact]

 * In case of accessing directories chdir to it directly instead of its
parent directory. This changes how dir symlinks are handled in root
shares and leads to avoiding the ACCESS_DENIED ISSUE.

[Test Case]

 1. Prepare smb server with a share:
[rootshare]
   guest ok = yes
   path = /
   wide links = no
   follow symlinks = yes
 2. On the server:
mkdir -p /srv/dir
ln -s /srv/dir /srv/symdir.
 3. Connect from a client:
smbclient -d 5 -m smb3 //server/rootshare -c "cd srv\symdir; dir"

[Regression Potential]

 * When accessing broken symlinks share's base directory is accessed.
This however seems to be consistent with a pre-fix behavior.
