Use deferred credits in XRPEndpointStep:

Browse Source 
The XRPEndpointStep bypassed the logic in deferred credits and
incorrectly counted funds acquired during a payment as available for
use in the payment. It also incorrectly used the current ownerCount when
calculating the reserve instead of the owner count as it was at the
beginning of the payment (reducing the owner count is analogous to
acquiring funds during a payment.)
