[net 13/15] net/mlx5e: MACsec, remove replay window size limitation in offload path

[Saeed Mahameed <saeed@kernel.org>]

From: Emeel Hakim <ehakim@nvidia.com>

Currently offload path limits replay window size to 32/64/128/256 bits,
such a limitation should not exist since software allows it.
Remove such limitation.

Fixes: eb43846b43c3 ("net/mlx5e: Support MACsec offload replay window")
