hd_geometry_guess() picks geometry and translation. Callers can get
the geometry directly, via parameters, but for translation they need
to go through the block layer.
Add a parameter for translation, so it can optionally be gotten just
like geometry. In preparation of purging translation from the block
layer, which will happen later in this series.

When hd_geometry_guess() picks a geometry, it also picks the
appropriate translation, but only when the prior translation hint is
BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior
translation would be passed to the BIOS whether it's suitable for the
geometry or not.
Fortunately, that can't happen. There are just two ways for the
translation hint to get set to something other than
BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=...,
and hd_geometry_guess(). Both set it only when they also set a valid
geometry hint, i.e. one with a non-zero number of cylinders.
Since hd_geometry_guess() returns right away when it finds a valid
geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in
the remainder of the function.
Assert this, and simplify accordingly.

bdrv_get_floppy_geometry_hint() fails to store through its parameter
drive when bs has a geometry hint. Makes fd_revalidate() assign
random crap to drv->drive.
Has been broken that way for ages. Harmless, because:
* The only way to set a geometry hint is -drive if=none,cyls=...
Since commit c219331e, probably unintentional.
* The only use of drv->drive is as argument to another
bdrv_get_floppy_geometry_hint(). Which doesn't use it, since the
geometry hint is still there.
Drop the broken code, ignore -drive parameter cyls, heads and secs for
floppies even with if=none, just like before commit c219331e. Matches
-help, which explains cyls, heads, secs as "hard disk physical
geometry".

Commit 4be23939ab makes ehci instantly
zap any unlinked queue heads when the guest rings the doorbell.
While hacking up uas support this turned out to be a problem. The linux
kernel can unlink and instantly relink the very same queue head, thereby
killing any async packets in flight. That alone isn't an issue yet, the
packet will canceled and resubmitted and everything is fine. We'll run
into trouble though in case the async packet is completed already, so we
can't cancel it any more. The transaction is simply lost then.
