RDMA/rxe: Replace paylen by payload

In finish_packet() in rxe_req.c a variable was incorrectly called paylen
instead of payload. Elsewhere in the rxe source payload is always used for
the RoCE payload length and paylen is always used for the UDP payload
length. This will cause unnecessary confusion.

Replace paylen by payload in finish_packet().
