[PATCH] net/mlx5: fix wait descriptor opcode for ConnectX-7

[Viacheslav Ovsiienko]

Since ConnectX-7 the special hardware capability to schedule
packet sending on specified time is provided. It uses special
WAIT WQE (hardware descriptor) with wait condition defined
by opcode. The CYCLIC_BIGGER was wrongly used instead of
CYCLIC_SMALLER. This caused arbitrary and stale time shift
in traffic scheduling.
