[PATCH] sched/topology: change sched_energy_mutex and sched_energy_update to static

[Tom Rix]

sparse reports
kernel/sched/topology.c:210:1: warning: symbol 'sched_energy_mutex' was not declared. Should it be static?
kernel/sched/topology.c:211:6: warning: symbol 'sched_energy_update' was not declared. Should it be static?

When the commit listed in the fixes tag happened, the sched_energy_mutex
and sched_energy_update variable accesses were wrapped by a function and
the variables were and still are only accessed in the topology.c file.
So change their storage class specifiers to static.

Fixes: 31f6a8c0a471 ("sched/topology,schedutil: Wrap sched domains rebuild")
