e1000e: Fix queue interrupt re-raising in Other interrupt

Restores the ICS write for Rx/Tx queue interrupts which was present before
commit 16ecba59bc33 ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1)
but was not restored in commit 4aea7a5c5e94
("e1000e: Avoid receiver overrun interrupt bursts", v4.15-rc1).

This re-raises the queue interrupts in case the txq or rxq bits were set in
ICR and the Other interrupt handler read and cleared ICR before the queue
interrupt was raised.

Fixes: 4aea7a5c5e94 ("e1000e: Avoid receiver overrun interrupt bursts")
