Revert the logic of io_ompio_sharedfp_lazy_open. The user now has to explicitely disable shared fp in order for the structures not to be allocated. Otherwise, resetting the shared fp e.g. in case the file was opened in append mode will not work correctly, the code could deadlock. Signed-off-by: Edgar Gabriel <egabriel@central.uh.edu>
