kbuild: Remove unnecessary -Wno-unused-value
This flag turns off several other warnings that would be useful. Most notably -warn_unused_result is disabled. All of the following warnings are currently disabled: UnusedValue |-UnusedComparison |-warn_unused_comparison |-UnusedResult |-warn_unused_result |-UnevaluatedExpression |-PotentiallyEvaluatedExpression |-warn_side_effects_typeid |-warn_side_effects_unevaluated_context |-warn_unused_expr |-warn_unused_voidptr |-warn_unused_container_subscript_expr |-warn_unused_call With this flag removed there are ~10 warnings. Patches have been submitted for each of these warnings.
