[ Upstream commit 7a0ea70da56ee8c2716d0b79e9959d3c47efab62 ]
Commit 43645ce03e00 ("qed: Populate nvm image attribute shadow.") added support for populating flash image attributes, notably "num_images". However, some cards were not able to return this information. In such cases, the driver would return EINVAL, causing the driver to exit.
Add check to return EOPNOTSUPP instead of EINVAL when the card is not able to return these information. The caller function already handles EOPNOTSUPP without error.
