libfdt: fix error code of fdt_count_strings()
Currently, this function returns a positive value on error,
so we never know whether this function has succeeded or failed.
For example, if the given property is not found, fdt_getprop()
returns -FDT_ERR_NOTFOUND, and then this function inverts it,
i.e., returns FDT_ERR_NOTFOUND (=1).
