net/mlx5: Allow async trigger completion execution on single CPU systems
For a single CPU system, the kernel thread executing mlx5_cmd_flush()
never releases the CPU but calls down_trylock(&cmd→sem) in a busy loop.
On a single processor system, this leads to a deadlock as the kernel
thread which executes mlx5_cmd_invoke() never gets scheduled. Fix this,
by adding the cond_resched() call to the loop, allow the command
completion kernel thread to execute.
Fixes: 8e715cd613a1 ("net/mlx5: Set command entry semaphore up once got index free")
