[PATCH 18/18] drbd: use semicolons rather than commas to separate statements

[Julia Lawall]

Replace commas with semicolons.  What is done is essentially described by
the following Coccinelle semantic patch (http://coccinelle.lip6.fr/):

// <smpl>
@@ expression e1,e2; @@
e1
-,
+;
e2
... when any
// </smpl>
