The libfdt functions are supposed to behave tolerably well when practical, even if given a corrupted device tree as input. A silly mistake in fdt_get_property() means we're bounds checking against the size of a pointer instead of the size of a property header, meaning we can get bogus behaviour in a corrupted device tree where the structure block ends in what's supposed to be the middle of a property. This patch corrects the problem (fdt_get_property() will now return BADSTRUCTURE in this case), and also adds a testcase to catch the bug.
