e1000e: Remove Other from EIAC
It was reported that emulated e1000e devices in vmware esxi 6.5 Build 7526125 do not link up after commit 4aea7a5c ("e1000e: Avoid receiver overrun interrupt bursts", v4.15-rc1). Some tracing shows that after e1000e_trigger_lsc() is called, ICR reads out as 0x0 in e1000_msix_other() on emulated e1000e devices. In comparison, on real e1000e 82574 hardware, icr=0x80000004 (_INT_ASSERTED | _LSC) in the same situation. Some experimentation showed that this flaw in vmware e1000e emulation can be worked around by not setting Other in EIAC. This is how it was before 16ecba59 ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1).
