Subject: [PATCH] lnwallet: check for correct value in HTLC outputs in
 commitment transaction

It is possible that that there are multiple HTLCs with different values,
but the same public key script. As such, a check against the value should
be performed when looking for HTLC outputs in a commitment transaction.
