e1000e: Disable TSO on i219-LM card to increase speed

[ Upstream commit 67d47b95119ad589b0a0b16b88b1dd9a04061ced ]

While using i219-LM card currently it was only possible to achieve
about 60% of maximum speed due to regression introduced in Linux 5.8.
This was caused by TSO not being disabled by default despite commit
6ed39afad32d ("e1000e: Disable TSO for buffer overrun workaround").
Fix that by disabling TSO during driver probe.
