i40e: Fix dropped jumbo frames statistics
Dropped packets caused by too large frames were not included in
dropped RX packets statistics.
Issue was caused by not reading the GL_RXERR1 register. That register
stores count of packet which was have been dropped due to too large
size.
Fix it by reading GL_RXERR1 register for each interface.
Repro steps:
Send a packet larger than the set MTU to SUT
Observe rx statists: ethtool -S <interface> | grep rx | grep -v ": 0"
Fixes: 41a9e55c89be ("i40e: add missing VSI statistics")
