USB: make the "usbfs_snoop" log more pertinent
USB: make the "usbfs_snoop" log more pertinent

This patch (as1261) reduces the amount of detailed URB information
logged by usbfs when the usbfs_snoop parameter is enabled.

Currently we don't display the final status value for a completed URB.
But we do display the entire data buffer twice: both before submission
and after completion.  The after-completion display doesn't limit
itself to the actual_length value.  But since usbmon is readily
available in virtually all distributions, there's no reason for usbfs
to print out any buffer contents at all!

So this patch restricts the information to: userspace buffer pointer,
endpoint number, type, and direction, length or actual_length, and
timeout value or status.  Now everything fits neatly into a single
line.

Along with those changes, the patch also fixes the snoop output for
the REAPURBNDELAY and REAPURBNDELAY32 ioctls.  The current version
omits the 'N' from the names.
