Old SMB1 servers without CAP_NT_SMBS do not support CIFS_open() function
and instead SMBLegacyOpen() needs to be used. This logic is already handled
in cifs_open_file() function, which is server->ops->open callback function.
So for querying and creating MF symlinks use open callback function instead
of CIFS_open() function directly.
This change fixes querying and creating new MF symlinks on Windows 98.
Currently cifs_query_mf_symlink() is not able to detect MF symlink and
cifs_create_mf_symlink() is failing with EIO error.
