MdeModulePkg/AtaAtapiPassThru: Restart failed packets
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3026
This commit adds code to restart the ATA packets that failed due to the
CRC error or other link condition. For sync transfers the code will try
to get the command working for up to 5 times. For async transfers, the
command will be retried until the timeout value timeout specified by the
requester is reached. For sync case the count of 5 retries has been
chosen arbitrarily and if needed can be increased or decreased.
