[PATCH] led: Do not overwrite label

[Christian Gmeiner]

label might have been set by a non device-tree based U-Boot driver already.

In my concrete case there is a PCI driver that uses device_bind_driver(..)
for different class types. The UCLASS_LED specific driver sets label
in its bind function.

Without this change the LEDs exposed by the PCI device are not available.

Fixes: 83c63f0d11 ("led: Move OF "label" property parsing to core")
