I assume the 'foldmethod' is being set by a modeline.  In that case you
need to execute the "zv" command with a BufWinEnter autocommand, but
only when the `" command was used.  That's because the BufReadPost event
is triggered before the modelines are processed.

This code should do it:

  autocmd BufReadPost *
    \ if line("'\"") > 0 && line("'\"") <= line("$") |
    \   exe "normal g`\"" |
    \   let b:doopenfold = 1 |
    \ endif
  " Need to postpone using "zv" until after reading the modelines.
  autocmd BufWinEnter *
    \ if exists("b:doopenfold") |
    \   unlet b:doopenfold |
    \   exe "normal zv" |
    \ endif
