[PATCH 6.1 025/114] net: phylink: move phy_device_free() to correctly release phy device

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Clément Léger <clement.leger@bootlin.com>

[ Upstream commit ce93fdb5f2ca5c9e2a9668411cc39091507f8dc9 ]

After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.
