SourceLevelDebugPkg DebugUsb3: Re-Fix GCC build failures

Browse Source 
Fix GCC build failures below.
variable 'EvtTrb' set but not used [-Werror=unused-but-set-variable]
variable 'Index' set but not used [-Werror=unused-but-set-variable]

The build failure could only be caught with -D SOURCE_DEBUG_USE_USB3
build flag.

ad6040ec9b5bbc462762331f9738b8e42c0b9c80 needs to be also reverted
when reverting IOMMU support patches, otherwise there will be conflict.
This patch is to re-do ad6040ec9b5bbc462762331f9738b8e42c0b9c80.
