net: stmmac: dwmac-sun8i: Fix EPHY clock leak in get_ephy_nodes()

get_ephy_nodes() stores the clock returned by of_clk_get() directly in
gmac->ephy_clk before the reset control is obtained. When the reset
lookup fails, the loop continues or returns without releasing that
clock, and sun8i_dwmac_probe() then jumps to dwmac_remove, which does
not call clk_put(). Keep the clock in a local variable and release it
on the error paths.
