Properly release key in spa_keystore_dsl_key_hold_dd()

Browse Source 
Since dsl_crypto_key_open() references the key, 0d23f5e2e4 should
have called dsl_crypto_key_rele() to drop it first instead of
calling dsl_crypto_key_free() directly.  The final result should
actually be the same, but without triggering dck_holds assertion.
