RDMA/rxe: Fix redundant call to ip_send_check
For IPV4 packets sent on the wire the rxe driver calls ip_local_out()
which immediately calls __ip_local_out() which sets iph->tot_len and calls
ip_send_check(). This code is duplicated in prepare4(). On the loopback
path the IP header checksum and tot_len fields are not used so they do not
need to be set.
Remove this redundant code.
