Subject: [PATCH] net/mlx5: fix secondary process resource leakage

[ upstream commit 09e0fd260e2e414134154b6e0e955c8424b51c0a ]

When running testpmd with an mlx5 device and then executing at testpmd
prompt in a raw: "port start all" followed by "port stop all"
a new file named /var/tmp/net_mlx5_<socket num> is created as a result
of creating a new unix domain socket (used for communication between
the primary and secondary processes).
When the new unix socket file is created the old unix socket file should
have been removed. This commit fixes it by closing the old unix socket
just before creating the new one in function mlx5_socket_init()

Fixes: f8b9a3bad467 ("net/mlx5: install a socket to exchange a file descriptor")
