Stephane Graber eb1ba8d1c3 drivers: net: xgene: Fix regression in CRC stripping ...

commit e9e6faeafa upstream.

All packets on ingress (except for jumbo) are terminated with a 4-bytes
CRC checksum. It's the responsability of the driver to strip those 4
bytes. Unfortunately a change dating back to March 2017 re-shuffled some
code and made the CRC stripping code effectively dead.

This change re-orders that part a bit such that the datalen is
immediately altered if needed.
