Marius Schilder 300403c83d cr50: avoid infinite looping w/ out of range inputs ...

Make the dcrypto ecdsa verify code check that r,s are in range, and
not depend on the caller C code to have done so.
For instance, s equal to 0 would result in infinite loop during
computation of its modular inverse.
