Lukasz Cieplicki 2b4659c145 i40e: Fix dropped jumbo frames statistics
[ Upstream commit 1adb1563e7 ]

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"
