[PATCH] ghes: don't return 0 even when failed to read estatus in ghes_proc()

[Ethan Zhao <ethan.kernel@gmail.com>]

ghes_proc() always return 0 even failed to read estatus, so when it is
called in interrupt handler ghes_irq_func(), we don't know the interrupt
was handled well or not, because the ghes_irq_func() will return only
IRQ_HANDLED.
