MdeModulePkg/UsbBusDxe: USB issue fix when the port reset
BZ #4456
Fixed a bug which led to an ASSERT due to the USB device
context being maintained after a port reset, but the
underlying XHCI context was uninitialized. Specifically,
Xhc->UsbDevContext is freed after a reset and only
re-allocates the default [0] enpoint transfer ring.
In order to avoid a memory leak, device enumeration is
performed after freeing the necessary buffers. This
allocates the Xhc->UsbDevContext for all endpoints of
the USB device.
