init: Fix link detection for auto-installation

The link state of a device needs to be detected when BOOTIF=link is
given on an auto-install.
Previously the link state of a device was determined in one pass. This
could lead to problems when it takes the hardware a while to initialize
or at least set the link state to UP.
Now five (5) passes are allowed to find a device with a link.
