Subject: net: mvmdio: disable/unprepare clocks in EPROBE_DEFER case

From: Tobias Jordan <Tobias.Jordan@elektrobit.com>


[ Upstream commit 589bf32f09852041fbd3b7ce1a9e703f95c230ba ]

add appropriate calls to clk_disable_unprepare() by jumping to out_mdio
in case orion_mdio_probe() returns -EPROBE_DEFER.

Found by Linux Driver Verification project (linuxtesting.org).
