1. wc_HmacSetKey() has a check against the hmac's type that assumes one
has called wc_HmacInit() on the object first. In FIPS Ready builds we
do not have wc_HmacInit() in the boundary. This change removes that check
and action when making a FIPS build. The free called doesn't do anything
in the FIPS build case.
2. Initialize the Hmac's macType to WC_HASH_TYPE_NONE. Check the macType
against that rather than 0. There are some build configs where none isn't
0.
