coinstats: Extract hash_type in-member to in-param

Currently, CCoinsStats is a struct with both in-params and out-params
where the hash_type and index_requested members are the only in-params.

This change removes CCoinsStats' hash_type in-param member and adds it
to the relevant functions instead.

[META] In subsequent commits, all of CCoinsStats' members which serve as
       in-params will be moved out so as to make CCoinsStats a pure
       out-param struct.
