usb: Avoid incorrect memory leaks reported by kmemleak tool. 



Certain memory allocations are not properly tracked by the kmemleak
tool, which causes it to incorrectly detect memory leaks. Notify the
tool by using kmemleak_not_leak() to ignore the memory allocation
so that incorrect leak reports are avoided.
