    perf namespaces: Fixup the nsinfo__in_pidns() return type, its bool
    
    [ Upstream commit 64a7617efd5ae1d57a75e464d7134eec947c3fe3 ]
    
    When adding support for refconunt checking a cut'n'paste made this
    function, that is just an accessor to a bool member of 'struct nsinfo',
    return a pid_t, when that member is a boolean, fix it.
