MdeModulePkg/XhciDxe: Non-zero start/stop values in XhcGetElapsedTicks
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4578
The implementation of XhcGetElapsedTicks did not account for
non-zero start and stop values for the performance counter
timer, potentially resulting in an incorrect elapsed tick
count getting returned to the caller. Account for non-zero
start and stop values when calculating the elapsed tick
count.
