[PATCH -next] net: lan966x: Do not check 0 for platform_get_irq_byname()

Since platform_get_irq_byname() never returned zero, so it need not to
check whether it returned zero, it returned -EINVAL or -ENXIO when
failed, so we replace the return error code with the result it returned.

For non-bugfix Networking patches, it is appropriate to
designate the target tree as 'net-next' rather than '-next'.
(For bug fixes 'net' is appropriate).

Otherwise, this looks fine to me.
