SourceLevelDebugPkg DebugUsb3: Fix GCC build failures

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.
