libfdt: Fix fdt_strerror() bugs
This fixes several small bugs related to fdt_strerror().
- an entry is added to the error table for FDT_ERR_BADLAYOUT.
- Incorrect usage of fdt_strerror() in check_property() and
check_getprop() is corrected (they were passing a positive error code,
when fdt_strerror() expects a negative code).
- Add code to properly retreive an error code from
fdt_get_property() in check_property(). With that a check that the
length returned by fdt_get_property() matches that stored in the
retreived property.
