[PATCH net] net: bcmgenet: fix error returns in bcmgenet_probe()

[Zhang Changzhong]

The driver forgets to call clk_disable_unprepare() in error path after
a success calling for clk_prepare_enable().

Fix to goto err_clk_disable if clk_prepare_enable() is successful.

Fixes: c80d36ff63a5 ("net: bcmgenet: Use devm_clk_get_optional() to get the 
clocks")
