[Patch 2/2] SecurityPkg/OpalPassword: Fix PSID revert no hint message.

[Eric Dong <eric.dong@intel.com>]

For no warning message when do the PSID revert action, the
message in the popup dialog is not enough. The error use
of NULL for CreatePopUp function caused this regression.
This change fixed it.

Passed Unit Test:
1. Check PSID revert with/without warning message cases.
