sh_eth: remove unchecked interrupts for RZ/A1

BugLink: http://bugs.launchpad.net/bugs/1650607

[ Upstream commit 33d446d ]

When streaming a lot of data and the RZ/A1 can't keep up, some status bits
will get set that are not being checked or cleared which cause the
following messages and the Ethernet driver to stop working. This
patch fixes that issue.

irq 21: nobody cared (try booting with the "irqpoll" option)
handlers:
[<c036b71c>] sh_eth_interrupt
Disabling IRQ #21
