net/qed: allow old cards not supporting "num_images" to work

[ 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.

Fixes: 43645ce03e00 ("qed: Populate nvm image attribute shadow.")
