clk: samsung: Fix memory leak in _samsung_clk_register_pll()
[ Upstream commit 5174e5b0d1b669a489524192b6adcbb3c54ebc72 ]
If clk_register() fails, @pll->rate_table may have allocated memory by
kmemdup(), so it needs to be freed, otherwise will cause memory leak
issue, this patch fixes it.
Fixes: 3ff6e0d8d64d ("clk: samsung: Add support to register rate_table for samsung plls")
