eth: bcmsysport: fix call balance of priv->clk handling routines

Browse source

[ Upstream commit b255ef45fc ]

Check the return value of clk_prepare_enable to ensure that priv->clk has
been successfully enabled.

If priv->clk was not enabled during bcm_sysport_probe, bcm_sysport_resume,
or bcm_sysport_open, it must not be disabled in any subsequent execution
paths.
