[POWERPC] iSeries: Fix unregistering HV event handlers

Commit fbd568a3e61a7decb8a754ad952aaa5b5c82e9e5 ("Change
synchronize_kernel to _rcu and _sched") changed the deprecated
synchronize_kernel() in HvLpEvent_unregisterHandler() to
synchronize_rcu().  It turns out that it should have been
synchronize_sched().
