routing: skip amtInRange for custom HTLCs

Browse Source 
We might be trying to send an invoice amount that's greater than the size of the channel, but once you factor in the custom channel logic, an actual HTLC can be sent over the channel to pay that larger payment.

As a result, we'll skip over this check if a have a custom HTLC.
