bnxt: add more ethtool standard stats

Michael suggest a few more stats we can expose.

$ ethtool -S eth0 --groups eth-mac
Standard stats for eth0:
eth-mac-FramesTransmittedOK: 902623288966
eth-mac-FramesReceivedOK: 28727667047
eth-mac-FrameCheckSequenceErrors: 1
eth-mac-AlignmentErrors: 0
eth-mac-OutOfRangeLengthField: 0
$ ethtool -S eth0 | grep '\(fcs\|align\|oor\)'
     rx_fcs_err_frames: 1
     rx_align_err_frames: 0
     tx_fcs_err_frames: 0
