sched/debug: Explicitly cast sched_feat() to bool
[ Upstream commit 7e6f4c5d600c1c8e2a1d900e65cab319d9b6782e ]
LLVM has a warning that tags expressions like:
if (foo && non-bool-const)
This pattern triggers for CONFIG_SCHED_DEBUG=n where sched_feat() ends
up being whatever bit we select. Avoid the warning with an explicit
cast to bool.
