MdeModulePkg/AtaAtapiPassThru: Revert patch to disable PCI attributes

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 the device
at ExitBootServices()"

This reverts commit 6fb8ddd36bde45614b0a069528cdc97077835a74.
