When ut test in this steps, will not call rte_vdev_init()
1. meson build
2. cd build
3. meson test compressdev_autotest

This use case tests the framework code and doesn't care about the specific device, so zlib device is randomly selected.
According to what you said, it may affect the command-line test. I need to think it again.
