In-flight DMA from 1st kernel could continue going in kdump kernel.
New io-page table has been created before bnx2 does reset at open stage.
We have to wait for the in-flight DMA to complete to avoid it look up
into the newly created io-page table at probe stage.

v1->v2:
    Michael suggested to wait for the in-flight DMA to complete at probe
    stage. So give up the old method of trying to reset chip at probe
    stage, take the new way accordingly.
Patch updates don't work this way.

When you update a patch that is part of a patch series, you must
resubmit the entire series anew.

Thank you.
