MdeModulePkg/EhciDxe: call EhcFreeUrb when int-transfer completes
It didn't cause big issues when VT-d was disabled.
But in VT-d enabled platform, lack of EhcFreeUrb call caused
the DMA data was not moved back to user's buffer.
It caused the correct data cannot be got through sync interrupt
transfer.
