If a 'clk_prepare_enable()' fails, then we need to disable_unprepare the
clk already handled.
With the current implemenatation, we try to do that on the clk that has
triggered the error, which is a no-op, and leave 'msm_host->bus_clks[0]'
untouched.
Shift by one the index array to free resources correctly.
