efebad0d67 Run extra complete in failure tests regardless.
We do not need to expect to fail, running another complete in either sign or
verify after successful completion should also return BAD_STATE.

de1114c883 Fix {sign|verify}_get_num_ops
Move the obfuscation of the internal library only returning a delta of ops done
into the driver wrapper, thus meaning driver wrapper and API call both return
absolute values of work done. Document the differences at the internal
implementation level.

c9774411d4 Ensure that operation is put into error state if error occurs
If an error occurs, calling any function on the same operation should return
PSA_ERROR_BAD_STATE, and we were not honouring that for all errors. Add extra
failure tests to try and ratify this.

f9c91a7fb5 Store the hash, rather than the pointer
For sign and verify, the pointer passed in to the hash is not guaranteed to
remain valid inbetween calls, thus we need to store the hash in the
operation. Added a test to ensure this is the case.
