[PATCH 7/8] cifs: move unix extension call to cifs_query_symlink()

[Sachin Prabhu <sprabhu-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

Unix extensions rigth now are only applicable to smb1 operations.
Move the check and subsequent unix extension call to the smb1
specific call to query_symlink() ie. cifs_query_symlink().
