scripts/coccinelle: update for compatability with Coccinelle 0.2.4
For doubleinit.cocci, Coccinelle 0.2.4 requires a comma after ... in a field list. Coccinelle also now behaves gracefully when a definition is provided for a virtual that doesn't exist, so there is no need for the semantic patch code to check for this case. Updated the documentation to reflect the fact that the best results will now be obtained with Coccinelle version 0.2.4 or later. Signed-off-by: Julia Lawall <julia@diku.dk>
