blockchain: Return early on nil utxo view in dbPutUtxoView

Browse Source 
This change is part of the effort to add utxocache support to btcd.

connectBlock may have an empty utxoviewpoint as the block verification
process may be using the utxo cache directly.  In that case, a nil utxo
viewpoint will be passed in.  Just return early on a nil utxoviewpoint.
