This patch allows Windows Mobile 6 devices to be used for
tethering -- that is, used as modems.  It was requested by
AdamW in kernel bugzilla:

  http://bugzilla.kernel.org/show_bug.cgi?id=11119

and Mandriva kernel-discuss list.  It is tested and confirmed
to work by Peterl:

  http://forum.eeeuser.com/viewtopic.php?pid=323543#p323543



This patch is based on the patch in the above kernel bugzilla,
which is from the usb-rndis-lite tree.

If the RTNL is held when we invoke flush_scheduled_work() we could
deadlock.  One such case is linkwatch, it is a work struct which tries
to grab the RTNL semaphore.

The most common case are net driver ->stop() methods.  The
simplest conversion is to instead use cancel_{delayed_}work_sync()
explicitly on the various work struct the driver uses.

This is an OK transformation because these work structs are doing
things like resetting the chip, restarting link negotiation, and so
forth.  And if we're bringing down the device, we're about to turn the
chip off and reset it anways.  So if we cancel a pending work event,
that's fine here.

Some drivers were working around this deadlock by using a msleep()
polling loop of some sort, and those cases are converted to instead
use cancel_{delayed_}work_sync() as well.

This patch should resolve a problem that's troubled support for
some RNDIS peripherals.  It seems to have boiled down to using a
variable to establish transfer size limits before it was assigned,
which caused those devices to fallback to a default "jumbogram"
mode we don't support.  Fix by assigning it earlier for RNDIS.
