[PATCH 5.9 171/255] lan743x: fix use of uninitialized variable

[Greg Kroah-Hartman]

From: Sven Van Asbroeck <thesven73@xxxxxxxxx>

[ Upstream commit edbc21113bde13ca3d06eec24b621b1f628583dd ]

When no devicetree is present, the driver will use an
uninitialized variable.

Fix by initializing this variable.
