Fix memory leak in mlx5_events_init(), in case create_single_thread_workqueue() fails, events struct should be freed. Fixes: 5d3c537f9070 ("net/mlx5: Handle event of power detection in the PCIE slot") Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

/*
* For dynamically allocated mm_structs, there is a dynamically sized cpumask
* at the end of the structure, the size of which depends on the maximum CPU
* number the system can see. That way we allocate only as much memory for
* mm_cpumask() as needed for the hundreds, or thousands of processes that
* a system typically runs.
*
* Since there is only one init_mm in the entire system, keep it simple
* and size this cpu_bitmask to NR_CPUS.
