Subject: libfdt: Remove no longer used code from fdt_node_offset_by_compatible()

From: David Gibson <[email-masked]>
Date: Mon, 18 Feb 2008 18:09:04 +1100

Since fdt_node_offset_by_compatible() was converted to the new
fdt_next_node() iterator, a chunk of initialization code became
redundant, but was not removed by oversight.  This patch cleans it up.
