Offending patch has changed the logic for handling default
configuration for dv_flow_en device argument.
This change has introduced a regression to Windows support.
On Windows, mlx5 PMD only supports flow API implementation
with dv_flow_en set to 1. With the change, this argument value was
changed based on device capabilities.
On newer NICs, dv_flow_en would be set to HW Steering flow engine
which is not supported on Windows.
On older NICs, it would be set to Verbs engine, which is also not
supported.
This patch fixes that by introducing platform-specific initialization
and fixup of relevant device arguments i.e., dv_flow_en and
allow_duplicate_pattern.
On Linux the existing logic is kept. On Windows dv_flow_en and
allow_duplicate_pattern are set by default to 1 (same as before
the offending patch).
