[ Upstream commit c626a438452079824139f97137f17af47b1a8989 ]
Now that global.turbo_disabled can only change at the cpufreq driver
registration time, initialize global.no_turbo at that time too so they
are in sync to start with (if the former is set, the latter cannot be
updated later anyway).
That allows show_no_turbo() to be simlified because it does not need
to check global.turbo_disabled and store_no_turbo() can be rearranged
to avoid doing anything if the new value of global.no_turbo is equal
to the current one and only return an error on attempts to clear
global.no_turbo when global.turbo_disabled.
While at it, eliminate the redundant ret variable from store_no_turbo().
No intentional functional impact.
