clk: hi3620: Fix memory leak in hi3620_mmc_clk_init()
[ Upstream commit bfbea9e5667cfa9552c3d88f023386f017f6c308 ]
In cases where kcalloc() fails for the 'clk_data->clks' allocation, the
code path does not handle the failure gracefully, potentially leading
to a memory leak. This fix ensures proper cleanup by freeing the
allocated memory for 'clk_data' before returning.
