USB: at91_udc: correct hanging while disconnecting usb cable
Correct hanging while disconnecting the USB device cable. Prevent a race
between vbus and UDP interrupts. This bug was tracked on at91sam9260ek
boards.
A usb resume interrupt was firing after the vbus interrupt : the IP was
then already stoped and not able to deal with it (no more clock). A simple
interrupt disabling is ok as the "end of bus reset" irq is non maskable and
ok to resume the USB device IP.
