Tue May 7 08:00:53 UTC 2019


After change behavior to send BlockSid command at EndOfDxe point,
check device ownership command will return un-authority error, it
finally caused opal driver can't show "Enable Feature" menu.

Update the code logic to send detect device ownership command
before send BlockSID command.
