In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns()
and mlx5_get_flow_namespace() must be checked to prevent NULL pointer

message with mlx5_core_warn() and return error pointer.

Fixes: ae430332557a ("net/mlx5: Refactor multi chains and prios support")
Same problem existed also in mlx5_esw_chains_create_fdb_table(), before
the refactoring.
Please refer to the original patch where issue was introduced, seems to
be commit 39ac237ce009 ("net/mlx5: E-Switch, Refactor chains and
priorities").
