[v1,01/18] net/mlx5: fix Rx hash queue creation error flow
Checks
Commit Message
The mlx5_hrxq_new function allocates several resources and if one of the
allocations fails, the function jumps to an error label where it
releases all the allocated resources.
When the TIR action creation fails, the hrxq memory is not released what
can cause a resource leak.
Add an appropriate release to the hrxq pointer in the error flow.
Fixes: 772dc0eb83d3 ("net/mlx5: convert hrxq to indexed")
Fixes: dc9ceff73c99 ("net/mlx5: create advanced RxQ via DevX")
