net/e1000: fix Rx error counter for bad length

Browse Source 
When the size of a packet in Rx channel is less than the minimum
or greater than the maximum, the packet will be simultaneously
counted by RLEC(Receive Length Error Count) and
RUC(Receive Under Size Count)/ROC(Receive Oversize Count) registers.

This patch fixes the issue of counting a length error packet twice
when counting the total number of received error packets.

Fixes: 70bdb18657da ("ethdev: add Rx error counters for missed, badcrc and badlen packets")
