[Bug 1936998] [NEW] e1000e blocks the boot process when it tried to write checksum to its NVM

Public bug reported:

[Impact]
While probing e1000e, it checks its NVM checksum, and write correct checksum back if the checksum is not correct. But for recent GBE update for security, its NVM could be written once for MAC address during production, so write checksum during driver probing is not allowed and would block the boot process.

[Fix]
Intel provides a fix for it.

[Test]
Verified on a Dell machine which has wrong NVM checksum.

[Where problems could occur]
From what Intel told us, the checksum isn't correct is not a big deal, we could ignore it and it won't lead to any issues.
