[Freedreno] [PATCH] drm/msm/dpu: initialise clk_rate to 0 in _dpu_core_perf_get_core_clk_rate

[Dmitry Baryshkov]

When removing the core perf tune overrides, I also occasionaly removed the
initialisation of the clk_rate variable. Initialise it to 0 to let max()
correctly calculate the maximum of requested clock rates.
