Subject: [PATCH][next] ixgbe: fix comparison of offset with zero or NVM_INVALID_PTR

From: Colin Ian King <colin.king@...onical.com>

The incorrect operator && is being used and will always return false
as offset can never be two different values at the same time. Fix this
by using the || operator instead.

Detected by CoverityScan, CID#1463806 ("Logically dead code")

Fixes: 73834aec7199 ("ixgbe: extend firmware version support")
