phylib: phy_attach_direct: phy_init_hw can fail, add cleanup
The function phy_attach_direct attaches the phy and calls phy_init_hw.
phy_init_hw can fail, but the phy is still marked as attached. Successive
calls to phy_attach_direct will fail because the phy is busy.

This patch adds phy_detach to clean up if phy_init_hw fails.
