e1000e: Do not auto-clear ICR bits which aren't set in EIAC
The spec does not justify clearing of any E1000_ICR_OTHER_CAUSES when
E1000_ICR_OTHER is set in EIAC. In fact, removing this code fixes the
issue the Linux driver runs into since 4aea7a5c5e94 ("e1000e: Avoid
receiver overrun interrupt bursts") and was worked around by
745d0bd3af99 ("e1000e: Remove Other from EIAC").
