[v2] test_compressdev:fix test case skipping due to missing device init

  The testsuite_setup function in the compressdev_autotest test case, 
the rte_compressdev_count() return 0 due to the lack of device init. 
It is considered that there is no equitment to skip execution. 
So add rte_vdev_init init compress_zlib device.

Why? Devices can be added as command line argument.
* Use ``--vdev="compress_isal"`` in the EAL options, which will call ``rte_vdev_init()`` internally.
See documentation of compressdevs.

And if at all it is required, why only the zlib, there are other devices as well.
