Use correct default value when comparing to `htlc_maximum_msat`

62f866965436fff1a8e98ee655a8a6dcbb8716c1 added two
`htlc_maximum_msat.unwrap_or`s, but used a default value of 0,
spuriously causing all HTLCs to fail if we don't have an htlc
maximum value. This should be mostly harmless, but we should fix it
anyway.
