After de/compress dequeue, the output checksum is copied into the op
structure. The "output_checksum" field in op structure is "uint64_t"
type, and the 32-bit checksums (CRC32, Adler-32) are copied into the
lower 32 bits.
When both CRC32 and Adler-32 are configured, CRC32 is copied into the
lower 32 bits and Adler-32 into the upper 32 bits.
However, in mlx5 PMD Adler-32 without CRC, is mistakenly copied into the
upper 32 bits.
This patch updates Adler-32 output checksun to be copied into the
lower 32 bits.
