USB: fix DoS in pwc USB video driver (CVE-2007-5093)
The pwc driver has a disconnect method that waits for user space to
close the device. This opens up an opportunity for a DoS attack,
blocking the USB subsystem and making khubd's task busy wait in
kernel space. This patch shifts freeing resources to close if an opened
device is disconnected.

Backported to 2.6.16.
