[PATCH] drivers: remove unused build variable

[Thomas Monjalon]

The variable fmt_name has been removed from DPDK 21.02-rc1.
Then some drivers were integrated in the same year with this variable.
Of this course it has no effect, so it is cleaned up.

Fixes: 832a4cf1d11d ("compress/mlx5: introduce PMD")
Fixes: a7c86884f150 ("crypto/mlx5: introduce Mellanox crypto driver")
Fixes: 5e7596ba7cb3 ("vdpa/sfc: introduce Xilinx vDPA driver")
Cc: stable at dpdk.org
