[PATCH] net: ethernet: ti: cpts: Fix refclk node leak in cpts_of_mux_clk_setup()

cpts_of_mux_clk_setup() takes a reference on the "cpts-refclk-mux" child
node that is only released on the mux_fail error path. When the mux clock
provider is registered successfully, the reference is leaked.
of_clk_add_hw_provider() keeps its own reference on the node, so release
the one taken here before returning.

Fixes: a3047a81ba13 ("net: ethernet: ti: cpts: add support for ext rftclk selection")
