[PATCH] clk: mediatek: clk-mt8195-topckgen: Fix error return code in clk_mt8195_topck_probe()

[Yang Yingliang]

If devm_clk_hw_register_mux() fails in clk_mt8195_topck_probe(), it should return
error code.

Fixes: deeb2af77cf6 ("clk: mediatek: clk-mt8195-topckgen: Register mfg_ck_fast_ref as generic mux")
