[PATCH -next] staging: fieldbus: arcx-anybus: Do not check 0 for platform_get_irq()

[Zhu Wang]

Since platform_get_irq() never returned zero, so it need not to check
whether it returned zero, and we use the return error code of
platform_get_irq() to replace the current return error code, for that
platform_get_irq() may return -EINVAL or -ENXIO.
