xurtis mcs: Clear ksConsumed when charging to revoked SC

mcs: Clear ksConsumed when charging to revoked SC 
When a revoke operation clears the current SC, that SC can't continue
operation past the subsequent preemption point. Presumably, that SC had
sufficient budget for each iteration up to the last and could have been
charged for the last iteration.

Simply setting the consumed time to 0 at the point where the SC would
have been charged is equivalent to charging the time to that SC priori
to its being cleared, including any accounting for overrun.
