IntelSiliconPkg VTdDxe: Report status code for VTd error 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1273

Current code only uses DEBUG() for VTd error.
This patch updates to also report status code for VTd error.

Test done:
Created case that has VTd error and confirmed the error
status code could be reported as expected.
