    nfs acl: bugfix, don't use static nfsd_acl_versions[]
    
    By the commit for v5.2-rc1,
    e333f3bbefe3 2019-04-24 nfsd: Allow containers to set supported nfs versions
    the line to copy a value from nfsd_acl_version[] to static
    nfsd_acl_versions[] was removed.  It is OK, but nfsd_acl_versions[] is
    still set to nfsd_acl_program.pg_vers which means pg_vers has NULLs for
    its all entires and nfsacl stops working entirely.
    I am afraid the removal of static nfsd_acl_versions[] was just
    forgotten.
