Allow no digest given to imply KM_DIGEST_NONE if it was authorized

The KM1 legacy support wrapper was to strict in requiring a digest to be
specified whey the requested purpose and padding combination did not
require a digest.

This patch allows no digest given to imply KM_DIGEST_NONE if
KM_DIGEST_NONE was authorized.

Also fixes a bug where key data was not correctly initialized in the
rsa_keymaster1_operation when KM_PAD_NONE was requested.
