Richard Weinberger ccada0157f sched: Fix sched_policy < 0 comparison ...

commit b14ed2c273 upstream.

attr.sched_policy is u32, therefore a comparison against < 0 is never true.
Fix this by casting sched_policy to int.

This issue was reported by coverity CID 1219934.

Fixes: dbdb22754f ("sched: Disallow sched_attr::sched_policy < 0")
