libfdt: Add missing RW_CHECK_HEADER to fdt_del_node()

Browse source 
fdt_del_node(), unlike most of the rw functions does not check the
fdt's header with RW_CHECK_HEADER.  However, it could make a mess of
things if the conditions in RW_CHECK_HEADER aren't met.  So, this
patch adds the omitted check.
