Important block fixes for 3.7

Hi Linus,

Distilled down version of bug fixes for 3.7. The patches have been well tested. If you notice that commit dates are from today, it's because I pulled less important bits out and shuffled them into the 3.8 mix. Apart from that, no changes, base still the same.

It contains:

- Fix for aoe, don't run request_fn while it's plugged.

- Fix for a regression in floppy since 3.6, which causes problems if no floppy is found.

- Stable fix for blk_exec(), don't touch a request after it has been sent to the scheduler (and the device as well).

- Five fixes for various nasties in mtip32xx.

Please pull.
