[PATCH] ut_test_compressdev:fix test case skipping due to missing device init

[Changsheng Wu <wuchangsheng2@huawei.com>]

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.
