MdeModulePkg: XhciDxe: Fix USB reset issue: use after free
`XhcFreeUrb` attempts to unmap `Urb->DataMap` after
`FreePool(Urb->Data)` has already been called in some cases, causing a
use after free. Change the ordering so `Data` is freed after `Unmap`and
only freed when appropriate.

MdeModulePkg: XhciDxe: Fix USB reset issue: callback / update order
As noted in the comment above the callback invocation,
the URB's callback may free the URB, so any
operations, including updates, must occur before the callback.
