usb: fixes for v4.11-rc4

f_acm got an endianness fix by Oliver Neukum. This has been around for a
long time but it's finally fixed.

f_hid learned that it should never access hidg->req without first
grabbing the spinlock.

Roger Quadros fixed two bugs in the f_uvc function driver.

Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather
difficult to trigger. When we're dealing with bounced EP0 requests, we
should delay unmap until after ->complete() is called.

UDC class got a use-after-free fix.
