Viresh Kumar dfc56ff5ec cpufreq: exit() callback is optional ...

[ Upstream commit b8f85833c05730d631576008daaa34096bc7f3ce ]

The exit() callback is optional and shouldn't be called without checking
a valid pointer first.

Also, we must clear freq_table pointer even if the exit() callback isn't
present.
