when a ifdef is used in the below manner, second one could be considered as
duplicate.
ifdef DEFINE_A
...code block...
ifdef DEFINE_A
...code block...
endif
...code block...
endif
In the scheduler code, there are two places where above pattern can be
observed. Hence second ifdef is a duplicate and not needed.
Plus a minor comment update to reflect the else case.
No functional change is intended here. It only aims to improve code
readability.
