USB: fixes for v4.14-rc5
A deadlock fix in dummy-hcd; Fixing a use-after-free bug in composite;
Renesas got another fix for DMA programming (this time around a fix
for receiving ZLP); Tegra PHY got a suspend fix; A memory leak on our
configfs ABI got plugged.
Other than these, a couple other minor fixes on usbtest.
