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.
