card: fix has_atomic if libdrm does not have atomic support
If libdrm was missing DRM_CLIENT_CAP_ATOMIC, but the driver still
supported atomic modesetting, m_has_atomic was set to true. The end
result was that test apps thought they can use atomic modesetting, but
it wasn't functional in the libkmsxx.
