Alexandru Gagniuc 76c78a5481 common: fit-sig: Fix error message in fit_config_verify_sig() ...

In fit_config_verify_sig(), when no 'signature*' subnode exists in
the configuration node, the fdt_for_each_subnode() loop is a no-op.
Therefore, no error flags are set, and 'err_,sg' is not populated
with an error string. This is incorrect behavior.

Populate err_msg to indicate that no 'signature' is found, before
entering the loop. The first call to fit_image_verify_sig() will
override clear err_msg, or set it to a more specific message.
