[svn-r7528] Purpose:
    Bug Fix

Description:
    The FPHDF5 code couldn't create a dataset then access it. Turns out
    that the "O_find_in_ohdr" code was protecting the object header which
    pulls it into the cache then unprotecting it. However, this caused
    the cache entry to be blown away and THEN we'd try to reread the
    entry (via AC_protect) but it didn't have all of the data that the
    find_in_ohdr function decodes for us decoded. It was also kind of
    unnecessary since we can just protect then call O_find_in_ohdr.

Solution:
    Removed the AC_protect and AC_unprotect from O_find_in_ohdr. Called
    AC_protect before calling the O_find_in_ohdr function.

Platforms tested:
    Linux (Fortran, C++)
    IRIX (parallel, Fortran)
    Sun (Fortran)
