Stephane Graber d5c7e1987c drivers: net: xgene: Fix regression in CRC stripping
commit e9e6faeafaa00da1851bcf47912b0f1acae666b4 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.
