MdeModulePkg/AtaAtapiPassThru: Revert patch to disable Bus Master
This patch caused Windows 10 S4 resume failure.
Considering the similar changes are reverted from PciBus driver,
revert the patch from AtaAtapiPassThru as well.
Revert "MdeModulePkg/AtaAtapiPassThru: disable only BM-DMA at
ExitBootServices()"
This reverts commit 76fd5a660d704538a1b14a58d03a4eef9682b01c.
