IB/ehca: In case of lost interrupts, trigger EOI to reenable interrupts

During corner case testing, we noticed that some versions of ehca do
not properly transition to interrupt done in special load situations.
This can be resolved by periodically triggering EOI through H_EOI, if
EQEs are pending.
