net/mlx5: fix Rx queue state update

In order to support DevX Rx queue stop and start operations, the state
of the queue should be updated in FW.
The state update PRM command requires to set both the current state and
the new requested state.

The current state and the new requested state fields setting were
wrongly switched.

Switch them back to the correct setting.
