This was originally patch as401 from Alan Stern.  This patch makes a couple
of small changes to the new scanning thread.

It changes the name to "usb-stor-scan", which was my original intention and
makes more sense than the current name.

It also removes the PF_NOFREEZE flag; if someone suspends their system
immediately after plugging in a USB storage device then the scanning thread
should be frozen along with everything else.  The delay will be restarted
after the system wakes up.
