net/mlx5e: CT: Use per flow counter when CT flow accounting is enabled

stable inclusion

--------------------------------

[ Upstream commit eed38eee ]

Connection counters may be shared for both directions when the counter
is used for connection aging purposes. However, if TC flow
accounting is enabled then a unique counter is required per direction.

Instantiate a unique counter per direction if the conntrack accounting
extension is enabled. Use a shared counter when the connection accounting
extension is disabled.
