drm/bridge: display-connector: fix an uninitialized pointer in probe()

Browse Source 
[ Upstream commit 189723fbe9aca18d6f7d638c59a40288030932b5 ]

The "label" pointer is used for debug output.  The code assumes that it
is either NULL or valid, but it is never set to NULL.  It is either
valid or uninitialized.
