crypto: ecc - Fix off-by-one missing to clear most significant digit
Fix an off-by-one error where the most significant digit was not
initialized leading to signature verification failures by the testmgr.
Example: If a curve requires ndigits (=9) and diff (=2) indicates that
2 digits need to be set to zero then start with digit 'ndigits - diff' (=7)
and clear 'diff' digits starting from there, so 7 and 8.
