Ingo Molnar f207dbe63c Revert "sched/wait: Suppress Sparse 'variable shadowing' warning" ...

This reverts commit 980f88e414.

This warning is actually useful, don't suppress it.

We actually rely on the shadowing for ___wait_cond_timeout().

We further used the __ret variable in __wait_event_timeout()'s cmd
argument: __ret = schedule_timeout(__ret). That now explicitly uses the
wrong __ret.
