compress/mlx5: fix compression level configuration

compress/mlx5: fix compression level configuration

The mlx5 compress PMD uses HW acceleration for the compress operations.
The mlx5 HW device has no level style mode, which does a tradeoff between
throughput and compression ratio, unlike SW drivers where the CPU is doing
the compress, and more CPU effort can cause a better compression ratio.
The mlx5 driver wrongly defined the Huffman block size configuration
according to the level that doesn't fill the level API requirement for
the tradeoff.

Remove the effect of the level configuration in compress operation.
