Re: [PATCH v3] of: overlay: log the error cause on resolver failure

When a DT overlay has a node label that is not present in the live
devicetree symbols table, this error is printed:

  OF: resolver: overlay phandle fixup failed: -22
  create_overlay: Failed to create overlay (err=-22)

which does not help much in finding the node label that caused the problem
and fix the overlay source.

Add an error message with the name of the node label that caused the
error. The new output is:

  OF: resolver: node label 'gpio9' not found in live devicetree symbols table
  OF: resolver: overlay phandle fixup failed: -22
  create_overlay: Failed to create overlay (err=-22)
