locking/atomic: scripts: fix ${atomic}_sub_and_test() kerneldoc

commit f92a59f6d1 upstream.

For ${atomic}_sub_and_test() the @i parameter is the value to subtract,
not add. Fix the typo in the kerneldoc template and generate the headers
with this update.

Fixes: ad8110706f ("locking/atomic: scripts: generate kerneldoc comments")
