[PATCH resend] testusb: remove all mentions of 'usbfs'

[Sergei Shtylyov]

Commit 8a424bf40d772fedacc91862ecc86f10541fabb3 (tools/usb: remove last USBFS
user) removed 'usbfs' files from the source but retained mentions of 'usbfs'
all over the place, most importantly in the misleading error messages printed
in case USB device files are not there.  Remove all the  mentions of 'usbfs'
for good now!

This patch is atop of 'usb-next' branch of Greg's tree...

Yes, I got that "usbfs files are missing" message on DaVinci recently, and it
sent me on the wrong trail for some time, so I'd like to egt this sorted out...

Resending as I messed out with KMail config. and not seeing the message in the
list archives...
