Alyssa Rosenzweig 84d8e6824b treewide: don't check before free
This was something that came up in the slop MR. Not sure it's actually a
good idea or not but kind of curious what people think, given we have a
sound tool (Coccinelle) to do the transform. Saves a redundant branch
but means extra noninlined function calls.. likely no actual perf impact
but saves some code.

Via Coccinelle patches:
