net/mlx5e: Make RSS indirection table size a constant
The indirection table size was defined by a variable that
was actually assigned a constant value.
Since we do not have any forseen intension to make it configurable
we simply made it a constant.
We also limit the number of channels such that the RSS indirection
table could always populate all RX rings.
