[ Upstream commit3b7180573c] In the CPU removal path the ->offline() callback provided by the driver is always invoked before ->exit(), but in the cpufreq_online() error path it is not, so ->exit() is expected to somehow know the context in which it has been called and act accordingly. That is less than straightforward, so make cpufreq_online() invoke the driver's ->offline() callback, if present, on errors before ->exit() too. This only potentially affects intel_pstate.
