Normally you don't want to rack the wine until mlf is complete. You may not have killed the bacteria with the sulfite, but you have certainly stopped it from working. You can either 1)(try to lower the S02 level in your wine and warm it up a bit to see if it will get going again on it's own or 2) lower the S02 and add some more mlb to get it going again or 3) treat it with lysozyme to stop it permanently and finish the wine up as is.
I would taste the wine and see how it tastes as is. If it is still sharp, then try either option 1 or 2.
This is just my opinion and hopefully we get some others weigh in here.
