[dpdk-stable] [PATCH v5 11/17] net/i40e/base: fix potentially uninitialized variables

[Robin Zhang <robinx.zhang@intel.com>]

The status of i40e_read_nvm_word is not checked, so variables set
from this function could be used uninitialized. In this case, preserve
the existing flow that does not block initialization by initializing
these values from the start.

Fixes: 8d6c51fcd24b ("i40e/base: get OEM version")
Fixes: 2db70574247b ("net/i40e/base: limit PF/VF specific code to that driver only")
