Subject: [PATCH] net/mlx5: fix return value of start operation

[ upstream commit 80554894c4618f6f3bd202565bc881215d99dde6 ]

On error, mlx5_dev_start() does not return a negative value
as it is supposed to do. The consequence is that the application
(ex: testpmd) does not notice that the port is not started
and begins the rxtx on an uninitialized port, which crashes.

Fixes: e1016cb73383 ("net/mlx5: fix Rx interrupts management")
