Add commit 3f2cee73b650 ("USB: usbfs: allow URBs to be reaped after disconnection") to -stable

[Alan Stern]

Greg:

The $SUBJECT commit was added in the 4.0 kernel, but I forgot to mark 
it for inclusion in the -stable kernels.  The problem it fixes is a 
nasty one, affecting people who use libusb: When a device is 
disconnected while a libusb transfer is in progress, libusb never 
receives a completion notification for the transfer.  This can result 
in a hang or a segmentation error, depending on how the userspace 
program tries to cope.

The patch may require some context adjustment before it will apply to 
the longterm -stable trees, but I think it should be added.
