net/mlx5e: Honor user choice of IPsec replay window size

Browse Source 
[ Upstream commit a5e400a985 ]

Users can configure IPsec replay window size, but mlx5 driver didn't
honor their choice and set always 32bits. Fix assignment logic to
configure right size from the beginning.

Fixes: 7db21ef456 ("net/mlx5e: Set IPsec replay sequence numbers")
