net/mlx5: IPSec, Fix a race between concurrent sandbox QP commands
Sandbox QP Commands are retired in the order they are sent. Outstanding
commands are stored in a linked-list in the order they appear. Once a
response is received and the callback gets called, we pull the first
element off the pending list, assuming they correspond.
Sending a message and adding it to the pending list is not done atomically,
hence there is an opportunity for a race between concurrent requests.
Bind both send and add under a critical section.
Fixes: bebb23e6cb02 ("net/mlx5: Accel, Add IPSec acceleration interface")
