qed: Populate nvm-file attributes while reading nvm config partition.

[ Upstream commit 13cf8aab ]

NVM config file address will be modified when the MBI image is upgraded.
Driver would return stale config values if user reads the nvm-config
(via ethtool -d) in this state. The fix is to re-populate nvm attribute
info while reading the nvm config values/partition.

Changes from previous version:
-------------------------------
v3: Corrected the formatting in 'Fixes' tag.

Fixes: 1ac4329a
