net/mlx5e: Expose and rename xsk channel parameter function

mlx5e_build_xsk_cparam() is meant to be the alternative
to mlx5e_build_channel_param(). It calculates only the parameters
that it requires using the previously configured mlx5e_xsk_param.

Move this function to params.c to be alongside
mlx5e_build_channel_param() and give it a similar name.

Expose the function as it will be needed by upcoming changes.

This patch has no functional changes.
