ice: Add a new counter for Rx EIPE errors
HW incorrectly reports EIPE errors on encapsulated packets
with L2 padding inside inner packet. HW shows outer UDP/IPV4
packet checksum errors as part of the EIPE flags of the
Rx descriptor. These are reported only if checksum offload
is enabled and L3/L4 parsed flag is valid in Rx descriptor.
When that error is reported by HW, we don't act on it
instead of incrementing main Rx errors statistic as it
would normally happen.
Add a new statistic to count these errors since we still want
to print them.
