hw/core: Fix fit_load_fdt() error API violations
fit_load_fdt() passes @errp to fit_image_addr(), then recovers from
ENOENT failures. Passing @errp is wrong, because it works only as
long as @errp is neither @error_fatal nor @error_abort. Error
recovery dereferences @errp. That's also wrong; see the big comment
in error.h. Error recovery can leave *errp pointing to a freed
Error object. Wrong, it must be null on success. Messed up in
commit 3eb99edb48 "loader-fit: Wean off error_printf()".
No caller actually passes such values, or uses *errp on success.
Fix anyway: splice in a local Error *err, and error_propagate().
